I bought this the other day and when it came I tried to put on to see how it fit but after doing so it just didn't look right. I'm installing a super T10 in a g body So I called tech support and talked to Jim he was very helpful. Well after talking to him I figured out how it was supposed to mount up for T10 in a 85 Monte Carlo SS. The left side of crossmember has to slide forward to where there are 2 holes in the frame there is a clip holding speedo cable and the front hole in member aligns with it.so you'll have to drill a hole for the rear hole of member. Can't wait to do some BURNOUTS!

Nice looking part

I had made my own double humped cross member years ago. I did not purchase one years ago because they originally weren’t made. Then as the first ones came out they looked awful. I stumbled across a picture of this one and on a whim I thought it was much better than the one I made years ago for myself. I got the crossmember in lightning time and looks and quality are very much like what I hoped for. Highly recommended.
