Angie's car has a non-original 8.5 inch 10 Bolt under it. It is currently a 2.73 open, so everything inside is junk. How hard is it to make a 8.5 10 bolt strong, and what do I have to do to it? I know that 10 bolts las a long time if they are built right, but what upgrades should I do to make it tough? Should I just cut down the Mopar 8 3/4 that I already have? I know it is very strong. Should I hunt up a Ford 9 inch? Spend even more for a 12 bolt?

Imho, it really need's to either have a real 10 OR 12-bolt under it, just like stock...

But that's just me........

Nothing's going to be stock here. The axle will like hang off a DSE kit.

angie's mechanic....

please, before you cut the 8-3/4, do a search in this forum for "8.5"; eleven pages of posts that i too am in the process of reading. a ton of great info from big gearhead. (and if it comes to it i'll even help fund a new moser for angie by taken that 8-3/4 off your hands!)

If power and traction will be high then the axle tubes will need to be welded. The plug welds on the 8.5 are junk and break easily if drag raced regularly. Here is information on welding the tubes. http://www.nastyz28.com/forum/showthread.php?t=18890&highlight=welding+axle+tubes

It's a B body rear with a 489 case. What would you do with that?

I'm still thinking about it. I may just go 9".
