No 100% sure which forum to post this in, but I drive an ls1.. so maybe its relevant I have a strange 12 bolt, and on BMRs web page it says the lca relocation brackets they have won't work on aftermarket rearends. Where can I get some that do? Or will I have to modify them?

Thanks!!

 

I know some companies make relocation brackets that fit aftermarket rear ends. I don't exactly remember which they are, but here's a few to try.

If you don't see any, I'd try to call/email cause I know somebody does make them.
