74 Duster bench to bucket ???
Whoever did the restore on my 69 used some b body buckets to replace the bench seat. They didn’t have any a body tracks since it was a bench seat car originally. There is a bunch of box steel and flat steel used to mount them. Works fine but took some improvising. The didn’t use the original mounting humps. Mine is a driver, so I am not real picky if it looks/ works good enough.
They also converted it to a console using a B&M quick silver ratchet shifter and a stock console. I didn’t like it at first but have gotten used to it. The auto floor shift parts and brackets are hard to find and I would guess harder to install. The B&M is a cable shifter so it is pretty easy to install. The column shift console was changed out for a floor shift one.
