Using 8 3/4 with /6

I don't reccommend welding spiders on any rear except a demo derby car. It totally sucks on wet or slipery roads. If you really want a limited slip, do it right, and replace the complete rear with a unit that has readily available parts. Several options, from low dollar to big bucks. Chose your poison.

PS: Greenmachine225, Please install a proper battery hold down. That car is too nice, to have a battery short or acid meltdown.
