I remember reading something bout a weld on kit for a rear axle that allows you to use a differet rear end if you would want to. Anyone know anything like this. I know it wil be a matter of time before my rear end blows and I dont have much money to spend after putting a big block in her.

 

I think the kit your referring to is the one from Southside Machine.
It contains subframe connectors,control arms that you weld to your rear axel and a crossmember that connects to your subframe connectors and your welded on control arms bolt to the crossmember.You won't need your torque arm anymore and it gives ya more room to run exhaust which you'll need if your useing a bigblock.From what I read the kits good for a drag car but your handling is not that great so I don't recommend useing
it on a daily driver.
