you should be able to take the trannt cross-member and motor pads to front cross member, out of any 60-73 v8 auto truck. Try a salvage yard close to you, 73+ might work too. You might have to knock out some rivets,but just use bolts to reinstall. GM was good to us these frames stayed relitivly the same for all these body styles. Even the coil sprung frames have all the same hardware holes.
