new rear half

well im finally thinking about doing a full custom rear end i was gonna do a wishbone setup i looked on fbi for the kits but didnt see them i also tried suicide doors but it wouldnt come up anyone have a link? also my rear end has a crack on 2 of the 4 link bar brackets so i was planning on getting a new rear end does any toyota rearend have disc brakes and fit in my truck like a stock rear end? thanks for help and also please post some custom rear frames

If I am not mistaken all Yota rears are about the same, with drum brakes

That is true but there are a few companies that offer the rear disc brake kits.......the only thing you can do is move to a car rear axle if you want the disc brakes already on the axle
