12 bolt on craigslist

The 67-72 4wd trucks had rear leafs, could be out of one of those. Only the 2wd trucks had the coil springs.

that is a 2WD coil sprung rear end. The long trailing arms hook to those perches w/ U-bolts and the panhard bar (shown) centered the axle in the frame. I used one of those in my 4WD though, simply torch the perches off and weld on new leaf perches to the top.

thanks a bundle it is starting to make sense now. can i cut the perches from my leaf sprung 12 bolt and weld them to the coil sprung rear or will the slight difference is shape/size throw it off. i am going with a flip kit in the rear so should i just buy the flip kit and just weld the "flip bracket" to the bottom of the rear end housing?

thanks in advance for everyones help.

not sure what the flip kit consists of but once you cut perches off, they are usually useless... I purchased a new set from summit racing pretty cheap, you might be able to go straight to the flip kit, most 2WD guys drop the leafs completly and run 4-link with airbags, coilovers or some other newer setup with tubular trailing arms and dropped crossmembers....
