These kits are designed to convert vehicles with original 364 V8 engines to Chevy automatic transmissions. In many instances, these kits will bolt on directly to the original parts but some may need some minor modifications. Professional installation is recommended for proper use of these parts. You are responsible to ensure parts are installed correctly to prevent unnecessary damage or wear to your parts. 

Changing the transmission will require changing the mount and driveline. Please compare all measurements and information before purchasing to ensure proper fit.
