Iceman, as namba wrote, you will have to do some fab work for the fit. You can: make a jig using 2x4's to represent the GT's current frame. Clamp on the beef-up metal (1/16" or 1/8") and suspend the motor over it. set some pvc pipe and cardboard on it to represent the firewall and tunnel. Alot easier to measure and figure this way. namba may have some notes on his setup. The jig for my 71 won't be set up til spring, or I'd help ya out on the info.
