Worked on the rear this weekend. The Trak lok I had picked up ended up being 4.56 and up (not the 4.10 and down we thought).
We scrambled around and were able to locate a 35 spline, 4.10 down, Power Lok (MUCH better LS) a couple hours away. We had the shop drop new clutch plates in it and picked it up Sat.
Dropped the R&P/carrier in that night and after a bit of cleaning and painting we slipped it under the burb.
It couldn't fit much tighter, we have about 1/2" clearance between pretty much everything...arm to rotor, tire to spring, tire to fender, arm saddle to caliper mount...I don't know how you could fit much more tire with a stock suspension/frame!!
We bolted everything in to gauge the amount of tubbing we're going to need and to work out the track arm/sway bar details.
