1966 Dart bucket seats

Thanks 65 Dartman. I suspected the frames were the same as what you mentioned but just to be clear to everyone the tracks themselves only fit 1966 model years, is that correct? I have an identical seat bolted into one of my 65 Darts but I had to drill at least one, possibly two new holes for the inboard track.

Yes, the tracks are 66 specific and for use in a 65-earlier A Body and 67, the user will likely have to drill additional mounting holes.

I am using the same frames in my 65 Dart wagon and to position the passenger side where I wanted it, I had to drill all 4 holes. I am using a power rack out of a 68 Chrysler that I added mounting nuts to secure the 66 frame to it. The rack fit perfectly in 3 of the 4 holes; just had to redrill one
