You should have 6-12 thou in end play. At 6 though you are on the edge of tight though.
The problem I find is forum import kids and how they did it. So you get people following bad advice. My son just did the swap and listened to Honda kids, stupid. He added it with an impact wrench and new bearings, no end play or shims. Well they all slap it in he says lol.
For clarity we bought new Timken bearings, not imported garbage. Actually pretty cheap like $20 for 2 bearings.
Get the Sonnax kit for shims.
Press the bearings on without shims and put it in the trans with end cups and no outer cover. Important, set the trans so the diff is vertical.
Using screw drivers and the end play gauge, lift the diff and measure end play.
Do the math and stack the .005 shims to get into the .006 to .012 range.
My sons car had no end play the way he put it in. He didn't get the bearings seated and was going to drive it lol. Then seated with new bearings it was .040. So he added .030 shims to get to .010 end play.
Look at the ring gear and add shims to the side that centers the ring on the pinion gear best.
Always add the new Belleville washers.
In the end with shims, bearings, washers, etc you are still around $500 and the mod is actually pretty easy. EVERY turbo Dodge should have had these stock so even if you want to keep yours stock but drive it, add the posi lol.
My trans is a bit more tough, need to figure out a 568 rebuild kit. Then I can get my hybrid done.
My sons setup is your best bang for the buck easy.

The diaphragm is 50% thicker for more PP pressure. They use 4 stock PP guide straps, vs 1 a piece. I just lost a T3/T2 clutch with a Sachs PP by snapping these. Then a really nice 4 puck disk with stronger springs. Really nice clutch for the money but requires big pilot shaft.
