Here is a common Ford PCV 1/2" grommet part 42065 available at most autozone, canadian tire, etc shops.  It comes close:

 

1/2" hole, 1" top curved face, 1.4" bottom face

I tried this (lacquer thinner) with a rock-hard side window bumper (the one that sits at the bottom-rear of the door).  It worked beautifully and I thought that I'd finally discovered the secret to rejuvenating all of the aging rubber parts on my car .  Sadly, after 24 hours I found that the rubber had returned to its original, rock-hard state.

I've tried three different 'rubber and vinyl restoration' products to date and none of them have been effective in softening hardened rubber (or vinyl).

I've read that a two step seems to work:

1. Lacquer Thinner to soften.

2. Wintergreen oil to soak

Here in Canada, a rust proofing liquid called Rust Check seems to soften rubber nicely in an unwanted fashion. It may work too:

I've got two originals I could send you. One is softer than the other. I guess one hardened over time. The overall height is the same but one has a bigger gap than the other.

Mike will be sending me the original for a factory correct reproduction....

 A couple of years ago we had a discussion about softening old rubber. Someone (I think it was 240260280) came up with a formula that softens and keeps the rubber soft after the solvent has evaporated. The formula was 1 pt. xylene and 2 ozs. of wintergreen oil. I mixed some up and soaked some old cracked, crusty hood bumpers for 24 hours. I tried flexing one as soon as it came out of the mix. It was nice and soft but crumbled when it was flexed. I waited 24 hours for some of the solvent to evaporate from the rubber and tried the flex test again. The results were much better. No crumble and a lot more flexibility. I found wintergreen oil to be very expensive however. In my notes on the subject there is a reference to "Thor Tire Prep #12". As I recall it is a tire conditioner (softener) used for racing. Might be worth looking into.

I did some searching too and found a lot of references to wintergreen oil. One post spoke about mixing about 4 oz of Wintergreen oil in a pot of water and boiling the parts for about 40 minutes. Evidently gave good sustainable results. Another was soaking parts in lacquer thinner mixed with wintergreen oil.

Just keep in mind Wintergreen oil is very toxic!

I found 8oz of oil on ebay for a little more than a $1 an ounce

[Namerow 467]

Hah!  I remember using wintergreen oil on the tires of my slot-racing cars back in the 1960's.  Nothing new under the sun, it seems.

As for trying it out now on old Datsun rubber, I'll wit for someone else to try that and report back.  I'm still not over the pain of the epsom-salts-and-vinegar electroplating set-up that was also 'guaranteed' to work.

Thanks everyone, I will be back tonight.

Again thank you everyone, nix240z, thanks joined , Mike B ‘s examples will work great, if you sell a replicated grommet , how much it is going to be ? I did not know wider gap exists, I guess the gap has to be tight to stay the grommet in place. 

I did not know the softening the rubber method, is it also used for classic car which it’s glass weather strip can not be obtained but needs to look nice ?

This looked very close to mine !

I will break down my original boot , cut every thread and spread the boot to see how the vinyl is shaped and sawed .

Hi Kats, that photo is from HS30 00004, I have not seen the grommet top part of the boot on an AU market car. I have to say it's also my favorite style. I have attached a photo of the boot from HS30 00150 which I assumed was just missing the grommet, but now that I see the photo of HS30 00004's in more detail I'm inclined to think maybe it never came with that grommet?

Hi Gavin, thank you for the photo of HS30-00150, it looks like a genuine leather. Maybe a dealer option at that time ? 

About HS30-00004, it looks it has an exact stock boot for me. I do not see any reason that Nissan would apply multiple type of boot according to its destination. I believe there was an only one boot for early models up to sep 1971 is , this one , thin vinyl  leather with the grommet, 75150-E4101.

Hi Kats,

I found 2 more photos of the boot after it was removed from the car.

Perhaps it's not OEM as you say and aftermarket? I always thought it was original but now I think you may be correct?

[Gav240z 230]

By the way Kats, have you seen this?

http://www.thezstore.com/page/TZS/PROD/classic08e01a/40-2502

[kats 969]

Gavin, yes I checked that one . Nice boot 

I wish it used more bold thread,  with wider parallel stitchings along the joint .

Kats

 

[kats 969]

Here is a development of the boot.

I think I can replicate 2 more from the vinyl sheet if I have the two grommets.

Kats 

[kats 969]

Each boot has each stitches. The NOS boot (shown on the left)  has decent stitches than my used boot. 

And this is the point , if it has decent stitches, you will see the square around the grommet.

I received the two grommets from Mike and I will be reproducing both. There is a slight .5mm difference in the heights of each.

 

[kats 969]

nix240z, that is a great news, I am looking forward to seeing a reproduction grommet. 

And thanks to Mike  provided sample grommets.

Kats

[nix240z 166]

The grommets turned out very nice.

Since there is a slight .5mm difference in the heights of each, I will offer both as a combo.

Thank you so much nix240z, it turned out very nice and lightning quick ! Even more coming with a bonus extra.

I am just amazed  of your ability of making products. I will place an order with some of your products.

Hi, seeing those conversations of  'reploduction' here and there, now something is coming up in my mind.

I am having fun to list parts which are NLA from Nissan and other venders today, not only that , I picked those parts up which are visible at a car show and are very likely missing or deteriorated through the years.  

I do not want nix240z to feel that he is obligated to do it. Do not take it seriously, just I want to show what is in my mind.

1/battery cable clip

2/fuse cover 

3/fuse cover stopper teeth 

4/flasher knob

5/early spare tyre holder rubber cover

6/luggage belt clip

7/door dove tail original style

8/ 1971 and later shoulder belt clip

9/seat belts clip

10/early shoulder belt anchor washers 

11/early tyre stopper rubber band

12/ early seat bottom side cover

1/battery cable clip - I have never seen this but could do this one. I would think it is metal with a rubber coating. More pictures and a size drawing would help out. 

2/fuse cover - the white lettering would be hard so leaning to no.

3/fuse cover stopper teeth - could do this one. 

4/flasher knob - I cant figure how to get the knob off

5/early spare tyre holder rubber cover - working on this one right now.

6/luggage belt clip - could do this one

7/door dove tail original style - no

8/ 1971 and later shoulder belt clip - could do this one

9/seat belts clip -could do this one

10/early shoulder belt anchor washers  - could do this one

11/early tyre stopper rubber band - would pass on this one, new urethane rubber does not like to be stretched for a long period.

12/ early seat bottom side cover - working on the set right now. 

 

I really comes down to what I need for my car  and then the demand. 

[gnosez 202]

While my two 240s are far from stock, every time I read a post showing NLA parts being reproduced makes me smile. Who knows I might have a third Z in my future, one I keep stock. Of course I would have to keep a third Z a secret from my wife.

A tip of the hat to nix240Z.

Nix240z,

I could loan you one of my battery cable clips to model after, as long as no disassembly 

is required.

Steve, for #1-battery clip I have examples I can send if you're interested. You are correct, it is metal covered with a rubber coating over it. Really glad to hear you are working on #12 - early seat guards. I've got originals for my four early cars but most are damaged to some degree. Another item to consider is the defrost blanking switch for the early cars with no defroster. Other markets like Australia and the base JDM S30 also had no defroster so they may be interested as well.

one step ahead of you on the defrost blank plug...in the mold as we speak...

Also I mailed your parts back today with your other order.
