Are these actually A body seats?

Those could also be had in 4 door cars. Do they tilt forward? The ones in 4 doors didn't but should be able to be modified to do so.

That's exactly what I did to put buckets in my Duster. 4 door car and had some latches cut that matched the factory latch closely enough.
