273 Commando - UTG

My understanding is they were “sort of” available in the late 65 model year.

I parted out a late 65 Dart GT (mid June build) with a 4 speed and had an 8.75 3.23 non-SG. The motor was gone but everything else was there in an extremely rusty body
Yes I do believe late 65. I got my 8.75 out of a 65 barracuda from the wrecking yard.
