Yes, experience does speak volumes, guess you missed that throughout most of my post

And from what I've also learned, old school guys can sometimes be THE worst source of remotely intellectual information for things these days. I give a lot of respect to them and know a whole fawk ton, but the things I've heard come out of many an old school person's mouth has made me laugh.

I swear if I hear how Carb's are superior to EFI, or how stainless steel is stronger than mild steel, and on and on...I'm just going to start walking away.

I think I'll go see if I can't find a set of revolver shackles to put on somehow now...

I agree with this. A SYE/CV eliminates harmonics at the T case end. Use axle shims to get the diff angle matching the driveshaft angle. Together these two will solve vibration issues.
You also need to keep the whole package, axle, shims, leafs, tightly bound together. I found double nutting the u bolts keeps things tight.
My setup has survived lots of Utah & Colorado trails, plus the 400 mile drives to get there.

can't agree more here. I have an RE 3.5, np242 on a 99. The tc drop shouldn't even be sold, if I knew what I know now, ide never have used a drop. This puts so much stress on your engine mounts, and likely causing minimal angle that the trans mount wasn't supposed to be supporting the drive train at.

I will be adding an sye one way or another, new mounts again, rear D'S, and maybe axle shims.
