72 Coupe Tunnel Heat Shielding

Was there a foam strip glued to transmisson bell housing on the 4 speed and the automatic?

Hi Edward,
I didn't find the remains of any glue on the bell housing of my 71. Since I didn't see any glue listed in the AIM UPC1 B7, I figured the pressure of the underbody was supposed to hold the collar in place.

Thanks for the response guys, was the placement of the foam strip just ahead of the foil backing ?thInk my foam strip was missing.

Alan/Edward: Good point about adhesive not being listed in B7, however, based on the drawing reference in the AIM, does it make sense that there was adhesive applied to the top of the foam shield, thereby bonding it to the body, not the belhousing? B7 shows only the shield and the cowl/dash panel, indicating to me that the shield was applied prior to body drop. What else would have held it in place? Do we have anyone with assy plant history?

I am sure one of the plant guys will respond, but I have seen photos of the foam "horsecollar" sitting on the bell housing as the body was being dropped. The foam could have arrived at the plant with adhesive already on it, like the radiator foam.

Plus, the bellhousing surface provides a better surface to bond the foam to. If the foam was glued to the fiberglass of the tranny tunnel, you'd have two pourous surfaces (foam + fiberglass) for the glue to contend with...
