Bucket seat tracks
The 67 seat back while being metal is thin, and if kicked most likely will dent.
I'm in a similar boat.
Buddy and I picked up a 67 Dart convert that was picked clean of the common parts. The unobtainium parts were all there. Go figure!
I'm researching bucket seats for it I found:
- 66 and 67 A body use the same seat frame
- 67 A and B body are the same seat frame as well
- 66 - 67 A and 67 B seat hard trim is similar, but the B has wider chrome at the top of the metal back.
- Obviously the upholstery is unique per car and year and trim package.
- As for slides (in this post) it looks like 67 -69 A body slides are interchangeable.
66 A body seats narrow chrome
67 A body GT seats narrow chrome
67 B body seats wide chrome
By the way ledendary has bucket seat spring kits.
I thought I saw that they also had reproduction seat frames.
