Well I've done it a few times on TF. Cross members I used are the universal tubular type. Several of our venders sell. Set carb mounting surface level. Locate/mock-up the motor and tranny to fit between firewall and rad. with eye toward tranny shifter location. then find steering box and headers while still mocked-up. Take front clip off for sure. Tweak all then drill for cross member mounting. Get a drive shaft made, Lokar shifter, and etc. Better advise from an AD 350 person will come along I'm sure.
