Martin, I've gone the similar route with my 76 Spit. I changed to the
plastic tunnel from TRF. But I insulated it with some neat stuff from
Home Depot. They sell a two layer bubble wrap lined with foil on each
side. It is called Reflectix and it is normally used for heating duct
insulation. I put 2 layers on the whole inside and then two more on the
front larger half. This was "glued" on with a tape that has no
backing...it's just glue. This tape (also Home Depot) is a lot easier
and much faster than using contact cement. Then I trimmed the edges with
2 inch wide foil tape. The finishing touch was adding strips of plastic
tape as an insulator over the areas of the tranny and overdrive switches
to prevent shorts.
I also made aluminum strips that fit on the outside edges of the tranny
cover to spread the compression area of the screws.
If you have read my post of about a month ago on "Hot Feet", you would
know that my feet were very uncomfortable. Now my feet are comfy and I
can enjoy the drive. I'd still like to have a fresh air flow but that
would mean cutting the fire wall, adding vent and hose.
I'm really happy with the results of the new cover and the insulation.
