After finding out that my transmission (TH400) needs a rebuild, I have reconsidered my rear end situation. I now want a 3.73 posi or open rear to compliment a 700r4 transmission. I currently have 3.08 gears in my GM 12 bolt rear.
- Is it possible to find a GM 12 bolt rear with 3.73 gears at a junkyard?
- If so, which year span of 12 bolt rears would fit my truck?
- If I rebuild my rear w/ 3.73, where in Austin, TX should I go? (heard of Inland?)
- Some suggest that I bring the parts, some suggest that I buy the parts through the shop that does the rebuild... Thoughts?
any feedback you may have to offer will be greatly appreciated.
