i should have been more clear, i was looking at the Procar seats the low back buckets.
I like the passenger seat flip option to have access to the back seat.
I didn't know if someone has done this change and how complicated it was
There's bunches of threads around here on seat swaps.
Use the search and look for posts from @BigBlue 94 and I think @BikerPepe` is restoring a second gen but not sure if he did the seats but... There's info all over the forum on this project.
Can't say for sure, not familiar with ProCar seats myself but you can fab up just about anything to work, with a little time and ingenuity. Very common for us to bolt different seat style up to the original frames to maintain that unique passenger seat forward tip. Obviously, low backs work best as some of the newer seats are a little tall and hit the dash before the seat is properly tilted. That's some... not all.
Including my own modification of an '08 SuperDuty bench seat swapped into my '73 F250. Not a Bronco but the method might help somebody, some day.
I've got seats to mount in my lil' lady's '78 but it's been so long since I picked 'em up, I'm not even sure what they were originally from. Maybe a PT Looser or something.
I have an 85 which has the same seat bases as yours i believe. I also had a totalled 2003 mustang mach1 with really comfy and race inspired bolstered seats from the factory. Black leather even!
To bolt them to my seat bases i had to drill a few holes in the seat frame and tap them. I think 4 of the 8 holes just had to be enlarged. They sat a touch low so I added a half inch nut to each bolt as a spacer. From removing the seats from the mustang to bolting them in my bronco was only a couple hour job. And now I have highback buckets with bolsters and headrests. Before, my neck would've snapped in an accident from the low back buckets.
