Havent read my JTR manual in some time but i'm fairly certain no cutting was involved. Changing to the JTR mounts will be more involved and costly as you will probably have to change certain things. (no more mechanical fuel pump, shorten the driveshaft, buy the mounts/kit) At the end of the day though there is no better time to do that then while the motor is already out and having the motor behind the front wheels will improve how the car handles.
