Oops, mismatched transmission parts, which to use?

[centralcoaster33]

Two part question.1. I have a 1997 transmission that came with my S14 and I have an older, maybe 1991 transmission from an S13 that I was using for a temporary replacement. Both are 5-speeds. Anyway, the throw out (release) bearing for each, gets pressed onto a bearing sleeve (release sleeve). I have two, each has a different height (maybe a 1/4" difference). The taller of the two appears to have been cast differntly and has a seam for each half. The shorter one has no casting seems. Which one should I be using in the S14 as I see a potential issue with clutch release.

2. I was taking apart the S14 transmission for a rebuild and carelessly let the sychro inserts fall out. There are three types, one set of 3 are like springs, another set are solid little metal guys with a groove cut into the bottom from end to end and the third set of 3 are solid metal guys with a groove cut into the bottom that stops short of the ends. Who knows where each set goes? I can tell where the spring one's go by the picture, but the solid types look very similar except one is about 1/2 mm longer that the other and the bottom grooves are slightly different so where do those go?

I know, they're tough questions... Anyone ever take a picture of their bearing/ release sleeve? A picture and a year might help.

Well, I was working on a transmission write up and luckily my photos are good enought to figure out the synchro inserts question. I still need help with the correct height of the throw out bearing sleeve for S13 and S14. I did think to look at clutch write ups and see their pictures hoping they specify which model their working on... Anybody know from experience?

Ahh, tech forum. The perfect place for crazy people to have conversations with themselves.
