Vic,
you seem thorough! Can you elaborate on how you attached the bubble
foil to the underside of the trans tunnel? I applied a layer to the
outside (under the carpet) because I was afraid that the stuff
wouldn't stay on underneath the car! I gotta pull the driveshaft soon,
and would love to install insulation UNDER the cover while I've got it
off.
TIA,
