Size Specs/Dimensions for 240Z Original Choke Cable Rubber Bellows?

[inline6]

A part that is almost always long gone on our 240z's, I am hoping to find a nearly identical to factory replacement "rubber bellows" for the choke cables for the car I am restoring.  Somewhere in my thousands of hours of web-surfing, I found this picture of some of the originals:

 

Does anyone have any originals that they could pull some measurements off of?  I am looking for dimensional details of both the boots and the collars/clamps that secure the boot to the cable and sheath.  I would like to fabricate the collars... but I need more info.

Here are some boots I am hoping are close enough:

Where did you find those?

I came across them after doing searches for rubber bellows.  It seems remote control boats use them.  Search "rubber bellows boat model" on ebay.  I had to buy a pack of 10, but they are cheap.

They look pretty close. Im not sure I would worry about getting closer than that

 

Edit: you might could scale the picture of the originals until the cable jacket is correct. Then take dimensions from the picture. We would do this all the time in Architecture

I think one of my spare sets still has bellows. I'll look.

Nice - thanks for grabbing those and a pic.  So, are you able to provide any details about the collars?  Looking at the pic, it seems there were differences in how tall the collars/bands were.  How thick is the metal they are made from?  Is there just one dimple on the circumference, or more than one?  Are they 6 sided?  They don't look round... which I find odd.  For the bellows, can you measure the rough overall length?  How wide are they at the fat part of the bellow, and at the thin part?  I have cables and can measure the outer diameter (OD) of the cable housing.  I just haven't done so yet.

I’ll give details in the morning. 

The collars are all hexagonal, some variety in them for sure. Bet they were round then crimped with a hex shaped crimper, kinda like a TV coax crimper.

Does your car have the new style choke cable assembly (1972) or the early 70/71 style? Looking at the BaT sale for your car, it looks like the early type. The early type did not have the rubber bellows. I know this because I accidentally bought a 1972 style choke cable assembly and had to remove the bellows to use it in my 1970. Even then it was a problem because the new style cables are shorter. If your car has three screw carbs they might work as I believe the linkage was different than the four screw carbs on mine.

 I ended up selling it and repairing my broken early cable. Here is a discussion from when I sold it on here,

Here are a couple more pics I took before I sold it.

 

For reference, here is an image from the parts book. You can see the bellows on the "new type" and none on the early one.

Interesting.  I may not need these after all.  I am looking at the fitment information.  How can I tell when the later type was utilized?  Assembly is #20 in the image:

I believe, It was started 09/71, the one I had was a 18410-E8803, but I think 18410-E8800 was actually the first version on the "new design" and it started 09/71.

Here is what my early choke cable assembly looks like. There is not enough room for the bellows after accounting for full travel of the choke.
