83-87 s10 5 speed, good but wrong spine count on imput shaft. good tail housing. ok overdrive.
Big Kahuna, there's a lot of variables here. Many different GM T5's were made. An S10 or Camaro will be different input spline from your stock tranny. The easiest way to find a clutch disc is to go to your auto parts store and look in their books. In my case, I knew what size I needed so I went to Autozone and looked in their book until I found an 11x1-1/8x26. The book lists actual disc sizes for varying applications. Some T5's are 14 spline, some are 26. As for output shaft, a TH350 yoke (among others) will work. Find a late 60's-70's truck at the boneyard with a TH350 and snag the driveshaft and yoke. I used my original back half of shaft and then had the front half from the boneyard cut and both pieces balanced together. This way, if I ever wanted to install my 4 speed again, I still got my original front half of driveshaft.
Camero/Firebird 5 speed better, but wrong tail housing. Better overdrive.
If swapping tail housings, you'll need to relocate the speedo drive gear on output shaft. Check the hybrid link a couple posts up. If you've got bucket seats, the Camaro shifter position is nice. Camaro's usually had .78 or better. In my case, I got a .63.
With a T5, I think the most important thing is determining gearing that will work for you. Drive your truck on the freeway a lot (me everyday!) and you'll want a nice OD. Don't worry about input shafts, there's a disc out there that will work whether it's for S10, Astro van, Corvette, Firebird, etc.
Hotrod6, I would guess those NV's from 90's trucks will have electronic speedos?
I recall past threads mentioning installation of electronic T5 and using a conversion box. Cost for the box is around $300. Opens up more possibilities but, too rich for me, my whole swap didn't cost much more than that!
