Summit transmission crossmember

[blue_eyes4dss]

I have a 1980 chevy monte carlo which has true duel exhaust. I had the crossmember modified for the duels. Now I am looking into the new transmission crossmember from summit racing (part# SUM-770300) for a TH-350 trans. My question is, does anyone have specs on this crossmember? I would like to double check measurements on the duel humps for the exhaust. Thought I could find a PDF file with specs, but no go. Can anyone help?

Wasn't sure where to post this question.

May get the Info by sending Summit an Email.

I call the tech line, not much help. Told me it would cost me the shipping to return if it don't fit.
