Rear Subframe Bushing - paper type insulator?

[enio45]

One my orig 69Z, there is a paper type insulator/sleeve between the floor and the top of the rear subframe bushing.

2 questions:

1. What is this for and should this be replaced as part of the restoration process?
2. Is there a source for these?

Thanks in advance for the advise.

Ed,
The "paper" is the tape that was applied over the two rear subframe bolt holes while the body was being tested for water leaks on the Fisher side. The tape was never removed after the tests and the subframe bolts pierced it during assembly on the Chevrolet side.
I believe it is a 2" black or dark masking tape.

I have some photos of some survivor ones.

James, thanks - i have some pics as well, but was not sure of the application.

Any paticular 2 inch black tape you have used for resto work?

"Heartbeat city" sells the tape, and various restoration marking paints.

Thanks Mike. I found something very similar to that on the 68 Yenko and was pretty sure that was what it was. Thanks for posting to pic.

Thanks everyone for the pics and info and advise....looks like another fine detail item to add to the resto work!

Thought I'd seen pics somewhere showing how top rubber bushing was taped to subframe, prior to body being bolted on.

Now I read where tape was on floor of body for a water test ??????

[enio45]

I would guess we can figure that out with the guys that have taken one apart - which side is the glue on?

Mike - any idea?

[m22mike]

The tape was for the water test and was sticky side up against the floor pan. The idea that the bushings were somehow taped up is an old wives tale as far as I know. Why would you tape a body bushing up side down when all you need to do is set it on the frame.
