i have a gm strut tower brace what brackets to i need to get in order to use it in the rear? any sugestions

No brackets needed

You need to elongate one hole on each end (either the forward or the aft holes)

Remove one mounting nut on each strut that correspond the the brace put the brace on reinstall the nut.

Good to go

Just watch those speakers they like to yank the brace outa your hand

so only one bolt per side goes on?

Yes only one.

humm... intresting... what would be the best thing to use to make the holes longer?? sugestions

A dremel, rat tail file, waller with a drill bit take your pick.

SWEET thanks alot im going to have to try that asap!!! i want it one im tired of it layen in my trunk not even set up

Yeah, they work better when they are bolted in

i know ... it keeps rolling fwd and hitting the back of my seat under hard breaking. lol i just havent posted to figure out how to do it
