Thanks Gdads51, yes I will address the brake line issue eventually. What I am looking for are ideas on what other “shade tree” mechanics have done to address putting a late model rear in these trucks, not necessarily a high budget build version. As you can see I have chosen options for a budget build. Ride choice is comfortable not farm truck suspension but also not road course style. Things I am looking at are ideas on the mounting of the axle below or above the leafs. Also the 10 bolt has 2 ears on top for trailing arms? Possible ideas on attaching these to 3100 frame…
