planning the 10 bolt build up

hello all,

well i know this has been talked about time and time again but im a bit different. i know that a good 9in is the best way to go hands down but. . . i want to learn how to build up and work on my 10bolt. i dont know much about what parts are interchangeable. all i know is that everyone says they are weak and not worth the money to build up. well that may be true but i still want to learn about the 10bolt hands on getting dirty all the fun stuff .

so i would like all the info about 10bolts. i currently have a 8.2, 2.56 ratio, with spider gears.

i know a bit about 10 bolts but not much. can i remove all my 8.2 parts and put in 8.5 parts or no?

ive heard that the axle tubes twist with hard lunches and a good fix would be to weld the tubes solid to the center section. that true???

the one thing i wont be doing on this build is installing the gears. ive read that you need not only the proper tools but it needs to be exact! thousandth of an inch exact! so id rather trust a shop my buddy owns here in town.

i do plan on going to the drag strip soon as i get the 10bolt built. ive done a bit of research and i have an idea of what i would like but i would like your input on what to look for. yes i should build the 9in but i want to learn the 10bolt

ive looked at the richmond gears 3.73, detroit locker, moser axles, and a summit support cover.

thank you for your time. all input is greatly appreciated

The 8.5 parts will not fit in a 8.2 so you will be stuck with the 28 spline axles. Welding the axle tube's is pretty common practice, Have someone who has a little experience do it so you don't end up with bent axle tubes.

You may be able to find a 12 Bolt open rear for your ElCo pretty cheap, then do all the upgrades. If you plan much strip use with sticky tires it would be better. The 8.2" 10 Bolt will last if it's not beat on to hard tho'. Had one in a 69 Nova that outlasted 3 engines with lots of strip use but I didn't put slicks on it.
Check out
If it's not listed they can get it.

They have great prices + Free S/H. I bought -- Axles + Bearings/Seals, 3-Series Posi Carrier, Gears, Master Install Kit, Solid Pinion Spacer, & Rebuild Video for my 12 Bolt, $825 Shipped.

The 8.2 will only accept 8.2 guts.... and they're getting scarce these days.
