Bellhousing Foam Collar
Does anyone have pictures of the foam collar installed? I've found a bunch of threads discussing it, but no pictures. I understand the general placement, but I'm curious exactly what it looks like installed. Thanks.

Hi 72,
On my 71 sb I put the collar where it's shown in the AIM.
The rear face of the collar is about even with the heavy seam between the firewall and the underbody.
UPC 1, Sheet A2 and B7.
Hope this helps!
Regards,
Alan

I have one in my 73, and it is actually up on jack stands at the moment (working on the A/C). I will try to get a pic for you later today.

According to my AIM 76 vette the collar is glued to the bellhousing 2.38" (approx 2-3/8") from the bellHousing face to the foam face. The instruction is located on sheet 15 in the undercoating section of the aim - towards the front.

Sounds right to me. I have one which hasn't been installed yet. The shape suggests if fits on the bell housing, between the bell housing and tunnel.

BINGO...a picture is worth a thousand words. There is no need to use any glue, start by slowly pushing the foam collar behind the distributor. Be sure to clear all lines and hoses as you go. Once it is in place, it won't go anywhere. Remember, the purpose of the collar is to keep heat from the interior through the trans tunnel. It also helps keep the transmission cooler and heat is a killer on transmissions. Good photo, but you need to put the collar in after you have the transmission bolted to the block. Notice, the collar blocks access to the bolts, hence it goes in last.

Sounds to me like a ~4' piece of pipe wrap from Lowes Depot would work fine....say for 3/4" pipe.....
I would use the heavier more black/dense foam with skin type....as opposed to the gray less dense foam....

The thick side goes on the drivers side, at lease it worked out that way on my 68, remembering that the engine is off set to the passenger side with a bigger gap on the left.
