Urethane bedliner products have a tendency to chip with high speed rock strikes. So i prefer of rubbery material (like the OEM undercoating). I need to recoat my rear axle. Its been sandblasted by lots of dirt road driving. The factory zinc plating under the paint has kept the worst of the rust at bay, buts its almost completely consumed now.
Brief update. Control arms all fit. I ended up tacking some 0.2" spacer/washers to the bushing body. I will adjust the model for a tighter fit, but this was expedient.
Diff and rack are fitted up. I am using the rack off the van, so this is an old worn rack for testing. I also bent and flared new hard lines for the rack, which clear the diff body. I also tested a 1/2" CV spacer, and it seems to be a good thickness. I may go with a 3/4" spacer, but that can be changed down the road easy enough.
Still no word on the rack adapters. They are supposed to ship next week currently... Wheels should arrive tomorrow. I am not sure if I will just transfer my current (almost worn out) tires, or if I want to take guess at what size will fit. Current thoughts are a 265/70R16. Though I think a 265/75R16 will fit if I remove the front mudflaps (they need to come off for other reasons). The safe bet is to mount the current 245/75s and see what clearance I have, both to body metal and suspension.
Current track width is looking to be 2-3" wider than original. Once I get it measured, I can get the rear adapters made. I think I will go with studs to match the front. Might as well be consistent. I have already had one bolt hole stripped by ham-fisted warehouse workers.
