How much should I shim my T-5's front bearing retainer?

Thanks for the offer. It's from a '95 Mustang GT.

Thanks for that link. Lots of good T-5 swap stuff there.

To measure endplay correctly you need to attach a dial indicator to the tailshaft housing. This is most easily accomplished with a magnetic base and a strip of iron or steel bolted to one of the holes for the shifter plate, because there's no ferrous material on the tranny housing itself. You give the tailshaft a whack with a dead blow hammer, then set the indicator on the tailshaft and zero it out. Then you smack the input shaft with your palm; the dial indicator will then show you your endplay.

I don't have a dial indicator, so that's why I'm trying to sneak up on the correct endplay with the .036, .034, and .032 shim packs. That's why I'm asking the question, basically, what do you guys who HAVE used a dial indicator, or who otherwise have a lot of hands on experience with rebuilding T-5's, feel when your endplay is correct. Do you feel noticeable drag with no wobble, or do you feel the slightest wobble and noticeably less drag?

I'm obviously within .004" of perfect, actually plus-or-minus .002", and I'm just trying to figure out which form of perfect is MOST perfect -- really tight, not as tight and no wobble, or noticebly less tight and the slightest wobble. It seems like you can get obsessive beyond all reason with clearances in the range of .002" and parts robust enough to handle 300 lb-ft and 150 mph -- a piece of paper is .004" thick -- but as long as the trans is out of the car and I have the shims to choose from, why not?

As far as running a '95 T-5 in a '65, I'm using the '65 bell with a spacer and a short input shaft. It's my understanding that the cases of the '95 and '93 Mustang T-5's are no different; it's just the bell that's different. So my setup will work.
