8 1/4 reabuild kits

[trevor74]

I am wondering if anyone makes rebuild kits for the 8 1/4 rearend. Everyone prefers the 8 3/4 cause its a better rearend but I am going to see if I can make due with what I have and see what happens. Ive ran into guys who have put 400 horse through an 8 1/4 without any problems and its whats already under my car so I was hoping some people could help me out.

thanks,
trevor
