I know the F-150/F-250 4wd Supercab frames are very similar.....are the 2wd's similar too?

I found a solid '76 F-150 Supercab 2wd....the brakes do not hold a candle to my '78 F-250 twin pistons.

Looking to swap in the F-250 (parts truck) suspension/brakes/rear axle/leafs/etc. to gain better brakes, heavier suspension, taller ride height.

Thanks!

the only thing that I know is different is the springs
