This adaptor kit uses a GM flywheel, Toyota flex plate and torque converter.
The flywheel housing is supplied which measures 74 mm/2.9" long. This housing has the GM bolt pattern on the front and the Toyota 3F 80 Series bolt pattern on the rear.
The kit has been designed to allow for firewall clearance without shifting the transmission or altering the drive shaft lengths.
The transmission torque converter is coupled to the flywheel via a crankshaft adaptor. The adaptor has the Toyota crankshaft bolt pattern and spigot diameter on the transmission end with the GM crankshaft bolt pattern and spigot diameter on the engine end. This allows the Toyota flex plate and torque converter to be bolted to the rear as with the old 3F engine. On the rear of the engine a manual flywheel is used instead of a flex plate, as there is no provision to support a flex plate when the starter motor is engaged.
