I picked up a set of rears off an 87 4runner today and a set of rears off a 94 T-100... I was gonna pull a set off a Tacoma but they were the exact same pack as the T-100.
The rears off the 87' are 48" and the T-100's are 54"... i'm going to add the T-100 leafs as needed to stiffin the springs as neccessary because the leafs are much thicker.
Plan on taking them down to bare metal tomorrow and giving 'em a fresh coat of paint. Then i'll start assembling the pack...
