So I inherited my dad's flat fender recently. This Jeep was built to race more than wheel in the early 80's, current powertrain is a Chevy 153 backed by an early iron case T10 adapted to a Dana 18. This works pretty good when you're ripping around barrels on 27 inch tall Goodyear Xtra-Tracs but it makes for a real miserable crawl ratio even for the 31s it has now, especially since I'm pretty sure it's got the stock WWII t-case that has a 2:1 low range.
The most expedient remedy I've come up with thus far is yanking the T10 and replacing it with a SM420 or 465 to get the extra low gear, but even the normal first gear in either one is lower than the current setup. Are GM 4 speeds standardized to the degree that I can bolt the truck transmission up to the current bell? I looked around parts catalogs enough to see that the clutch splines are the same but info on the early T10 is all buried by info on the later models.
