my humpback measures approximately 48" at the door post and 46" in the center of the doors. i'm going to try to use the middle buckets [gray leather] out of my old 95 caravan. they are approximately 20" wide. this gives lots of room for the doors, but since my driveshaft hump will be rather high, i expect some slight mounting problems to crop up. also, since the roof is chopped, i expect i may [probably] have to lose the headrests. the nice thing about my deal is the fact i don't have a back of a cab to interfear with the seatback angle or foot room.
