I've got it about 90% back together. Just have to button up the exhaust, front driveshaft, skid plates, add fluids and try it out. Should be moving tomorrow...... hopefully. Benchpressing the transfer case up and in is becoming easy.

The online instructions say it is optional to remove the check ball for firmer lockups. I won't be pulling the trans just to do that anyway. Didn't get any instructions in the box with the TC.
Just found out that the bolts that came with the TC are the wrong size. M8 instead of M10 and too long. Online instructions say M10 X 1.5 X 12mm. I was using the cut down OEM bolts before but they are too long now(about 18mm). Wouldn't be able to pull the TC tight against the flexplate before they bottomed out. Couldn't find anything shorter than 20mm tonight.

Your PI converter should measure 6 5/8" as pictured in my post above showing the OEM TC.
What I'll probably end up doing is measure my stock converter when I remove it and directly compare that to PI measurement and go from there.
thanks again for the very useful info guys

KySilverado: have you talked to a GM tranny guy just to triangulate the data a little more?

Yes, speaking with Chuck who had had a discussion with PI, they now say the space is okay.
