273 Commando - UTG

You could get an 8.75 in a dart or barracuda

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
