So today's question... The grommet in the original shift boot is not symmetric. It has a flat side, and a more rounded side. Which way was it originally installed? I've seen pics of original boots that seem to show the flat side up, For example, here's a pic of an original boot and a reproduction (made number of years ago by a member of the forum): And here's one from Roo's recent thread about his 3-D printed shift knob: But I've also seen pics with the more rounded side exposed (up): So what say ye experts of the originality? What is the correct original orientation of the grommet? Here are the threads those pics came from: https://www.classiczcars.com/forums/topic/38329-shifter-boot-alternatives-anyone/page/2/#findComment-344979 https://www.classiczcars.com/forums/topic/69522-3d-printed-gearknob/#comment-678725

Thanks guys. I will jettison those two parts.

E31 is “right” for your 71. N42’s were from 75 onward. E88’s were 72-74

Hello everyone, maybe somebody can help me? My 1977 280z is running rich at idle and the idle mixture on the AFM doesn't seem to help. I spend the last few days cleaning the electrical connections and timing the ignition again as it was out of spec. The car runs way better but the AFR gauge I temporarily installed still shows 11,5 at idle. I'd like to bring that down (or up depending how you look at it) to 14,7 as the car stinks of gasoline. The previous owner mentioned that the car running rich was the reason it didn't pass inspection (auction company didn't mention it had no valid inspection on it, APK over here in the Netherlands). After cleaning all the connections and checking the timing I tried messing with the idle air mixture screw but that didn't help. When turning clockwise a bunch the car did start to run richer at some point but when turning anti clockwise it didn't get past 11,5 AFR. Can anybody help me diagnose the problem? I would really like to drive the car on the road before the winter stop (oldtimer insurance). Also still waiting on some parts from Zservices EU but some are on backorder. In my quest to make the car run as it should I did notice the ignition coil is a 1,5 ohm unit with a total resistance of 2 ohm with the external resistor. I believe it needs to be closer to 1 ohm total so I'll probably replace the coil with a 0,5 Ohm one. Can somebody confirm this?

Hi all, When removing SUs how do you convert the 3 way heater pipe to 2 way? A 5/8 to 3/4 4" pipe with a 45 would be a dream come true so the heater core hose isnt bent for a straight pipe reducer but I've searched for days with no luck. Im not sure there is enough material in that pipe to tap a plug and I dont really want to use a cap. Any ideas I would appreciate it! Cheers

Not quite a unicorn... but pretty close. Current bid is $205. I predict it'll take over $750 to buy these.

Not the shipping tie downs but the ones that attach to frame maybe? Googled showed some similar when I searched... https://www.google.com/search?q=240z+tie+down+points&sca_esv=06dd4c047f376356&rlz=1C1VDKB_enUS1121US1121&udm=2&biw=1229&bih=556&ei=F8a0aJ7AG4b-p84Pzf-V8Qc&ved=0ahUKEwjep42dhraPAxUG_8kDHc1_JX4Q4dUDCBE&uact=5&oq=240z+tie+down+points&gs_lp=EgNpbWciFDI0MHogdGllIGRvd24gcG9pbnRzSP4gUKwHWIYccAF4AJABAJgBS6AB5QOqAQE3uAEDyAEA-AEBmAICoAJLwgIGEAAYCBgemAMAiAYBkgcBMqAH-QKyBwExuAdJwgcDMC4yyAcC&sclient=img

A good one. And you can't even here the Beatles.

Does anyone recognize these Tow or Tie Down Hooks / Rings as being a Datsun part? Thanks, Keith

How is that any more than just a guess - like the "I'm turning down the knob 2 1/16 turns"? Don't you need to know the AFR created by adjusting the jet position? And isn't the position different for varying temperatures and elevations?

Pretty easy to do, simple scaling down of a surfboard caliper would do the trick. If I get time I'll design one up this week. here's a couple of basic designs.

Would calipers not work?

I’m surprised that a gauge to measure the depth of the jet in the Z SU ‘s hasn’t been created. Seems like a little spring loaded gauge inserted in the jet track to expose depth of the jets would be simple for some of us that sell cool products ( 3D printing) on this forum. It would eliminate “how many turns down” which is kind of a screwy way to get where you want to be on your mixture. Anyone agree?

@smdvr67 I would delete your personal contact info. Bots crawl the web looking for info like this! Only share personal info through Private Messaging / PM's

The first part looks like a bracket for a spring perch for leaf springs. Don't believe either are Z parts...

Right now it's on the motor, but I was surprised at how the empty cavities will flash rust in high humidity. I'm sure I will always have the obligatory rust. Hopefully some small bolt somewhere,. A speck is a sufficient qualifier... ;)

Both parts... NOPE not a z part.. jmo.

Recently swapped my 1.5 ohm Petronix Coil and 3.0 0hm resistor with a MSD Blast coil with no coil. Car runs much more better and does not hesitate on traffic jams. Problem is tachometer is not working. How can i fix this?

Probably a pretty elementary question for this learned forum, but for my 240Z, HLS3028726, which is the correct cylinder head , N42 or E31? I have two of the former and one of the latter. Many thanks, Richard

240Z rear control arm. Powder coated black. Straight. $25 ps Trying to get my garage and desk organized, I plan to list one part, with photo, every day.

@Mike , There has been more spam added to the post by the bot.

So I have a couple mystery parts. Not sure if they are Z related or not. Anyone able to identify these? Here's the first: And here's the second. Looks a little like an over-rider bar, but it's not:

Today's event... I put more gas in him than I ever have before. I put five whole gallons in. And nothing seems to be leaking out!!! Proof!
