65 Barracuda #'s car question

As Chryslerfat said, the slant and 4 speed was possible in an early A Body. An 8.75 was possible in a late 65 but not likely with the slant 4 speed. I parted out a 7/23/65 build 65 Dart GT with a 273/235 4 speed combination that had a 65 date coded 8.75 in it.

There were no "matching numbers" until about 68 or so. If the "numbers" are important to you, the closest you can come is the build date of the different components which should be a month (or maybe more) before the actual build date of the car (which is on the fender tag).

Hope this helps a little.
