I used 1973 duster seats in my 1971 Duster due to the 1973 weighing less than the 1971 did I'm going to say that all the A body buckets from 1967 to 1976 will fit in those holes
The buckets from any 72-74 ABor E. The seat brackets are kind of hard to find. I have some 72 seat brackets that are in good shape. Pm if you want to discuss them.
I was wondering if seats other than A, B, is E body. I’m looking at a Duster with Shelby Daytona seats in it. It’s a project car and they “look” normal in the car. I was just asking to see if anyone knows that they actually fit.
Any seat will fit if you make up some adapters. I got some Daytona seats for my Jeep and they are really wide compared to a Duster's. I have some 89 Jeep leather buckets in my Demon while I recover the originals and those are great, size wise. I have the stock rails in and made some adapters.
If you are looking for bolt in including rails I have heard early 80's dodge Omni stuff is close.
