End-play of the main shaft and input shaft is a very important issue.

The ideal combination is 0.72 overdrive with a 3.73 or 3.90 rear differential. The 0.63 OD is rather tall but an engine with plenty of HP can handle it. The 0.86 OD gear will work well with a 3.08 rear axle. The difference between a non-world class and world-class transmission strength is minimal and should not influence your decision.

Almost all 1993 and earlier S10 T5 cases have a Muncie pattern. Feel free to contact me with your T5 questions.

So far, I have a 0.72 overdrive and the stock 3/4 ton gears, 4.57, I believe. I'm on 16" wheels with very tall sidewalls...not sure of total height, but gotta be darn near 3 feet.
