Good mornin' & happy Spring. I wondered if anyone had done a driveline swap in a '61 - dropping-in a later engine & trans combo? If so, are motor & trans mount locations the same in later 383/440 cars? I'd like to combine a '67 440 driveline with a 300G shell. Other than adapting the shifter mechanism & e-brake, is it a bolt-in application? Are there pre-fab kits available for joining the push-button shift? Many thanks.
