67 Ranchero Unibody spec's

I want to have the local frame shop check to make sure the unibody is not bent or tweeked too bad. I called two local frame shops but they don't have any spec's for that old of a vehicle. Does anyone know where I could get the spec's? I tried Googling but could not find anything. Any help would be greatly appreciated.

Jimmy Jet,
Let me have a couple days to dig through all the reference material I have and I'll see if I can find the specs you need..

Thanks, D.B.
I'll wait to hear from you.
