Just thought I'd jump on for an update. I had a 4.27 diff I was using which was actually nice. Nice pull in 1st and 2nd, and now that I've switched back to a 4.10 I'd say a noticeable difference in grunt off the line just a little buzzy on the highway. The only problem was the backlash felt a little excessive. Dan, from diffsonline.com put together a 4.10 LSD REM polished with some custom ramp angles and it is sweet! Dan's customer service was great. Maybe someday I'll send the 4.27 in to be rebuilt (unless someone else wants it, odds are its going to just sit around).
We've got a couple thousand miles on the rebuild. The car is an absolute blast to drive now. I'd say better than new for sure, at least as best I can remember. That was after all almost 24 years ago that we bought it. I'm on the fence about the power steering delete. Some days I like it, others not so much. We've had the coolest summer on record which has not fueled my motivation to track down why the A/C no workey. At least now it's just little things to work on. So with that I think I'll close down my posts on this thread and begin to look for my next project. Thanks for everyone's help and encouragement.
