Body Mount Tape - Width

[68camaroz28]

The radiator support bolts are not the same size, they are a smaller thread size by 2 sizes or so. 
The main subframe to body bolts must be 5/8" threads and I believe the rad support are 7/16.

Has anyone ever seen the tape still covering the rear shock mount holes?

Just checked mine quick - nothing there.  Shocks are not original and that area of the car would get a lot mortar/moisture disturbance from the rear tire.  As brittle as my subframe tape is, I'm guessing the rear shock tape would not survive.

Kind of hard to measure but it seems the width of the cushion is about correct. Have to admit I used the available width Lloyd. Here is a picture of Skip's 69 mount and tape and believe it gives a fair assessment of width.

Still looking for a more data points from original cars to confirm the tape width. I've asked the current owner of my former 10 10 RS/Z to measure and photograph the tape on that car and hope to hear back from him soon. Below is a photo I took of Skip's 69 survivor during MCACN Vintage Certification judging which is a different angle from Chick's photo and further suggests the tape was (at least) the diameter of the sub frame cushion.

I've seen (and saved somewhere) photos of this detail but not observed it in person. Noted it because I was looking at the original shock absorber cap detail at the time.

I measured an NOS cushion at about 2 1/2 inches (non compressed) vs the parts vendor body mount tape which measures just 1 1/2" and it just doesn't seem wide enough. Below is a photo of my subframe with the parts vendor tape.

  AMK sells 2" (7 mils thick x 2" x 180') black masking tape under p/n B-11665 for $12. That's what I used on my resto.

Photos of the subframe cushions from the 10 10 69 RS/Z weren't helpful.

Thanks Mike, 2" black crepe paper tape seems to be the way to go, the widest width I've found is also 2"(in ~7mil thickness). Also available on Amazon for a slightly lower price.

Wouldn't think masking/paper tape would prevent water ingress?

True but then it only needed to "live" for 3 minutes.

This is what I used and believe I got it from Quanta, primarily a corvette parts house. Note its about the same size as the cushion Lloyd!

Chick, I previously checked Quanta's site as I have had dealings with them before and could only find the same width 1 1/2" tape other vendors sell? From their product listing:

Body Mount Shim Tape - 1-1/2" wide Black
Applications: 1965 Corvette: Corvettes and other cars had their body mounting shims or mounts held in place with special tape while the body was dropped onto the frame. This tape is thicker than standard masking tape
Quantity: 1 roll, black
Packaging: Boxed
Part Number: 03-10

Is there another tape width they sell?

Just made a quick check of the garage and not finding what I used if I had any left but will do some more checking. Thought it came with their paint/marking kit but not 100% sure Lloyd. If I can find anything out I will report back.

Chick I couldn't help but notice the bushing in your photo appears to have the integrated washer which would be the 3928380 instead of the 3901361 bushing or is that camera flash?
