66 Valiant Wagon firewall gaskets/grommets

Ok all,

I'm just starting on the slightly modofied/restoration of cherished 66 plymouth Valiant wagon and I have a couple questions.......

The basic body shell of the 66 wagon is a carry over from the 65 wagon correct? I assume so since it has the same rear bumper and wheel openings of the 65.

I'm in search of a replacement firewall gasket set and I'm looking for a replacement firewall grommet for the gas pedel shaft (swivel, slant 6 design) and the rubber bushing for the gas pedal shaft into the carburetor.

Any leads on these would be greatly appreciated.
