Hi Etienne Tom here, if your car has right hand drive like the original , follow my lead I have a 1965 GT40 with a Porsche 996 transmission
which has cable shifting. It ties into my block with a Kennedy engineering adapter plate . To make it work you have to flip over the
transmission pull out the vent plug with a pair of pliers tap it with a 1/4" pipe tap and the oil fill will now be the drain , and the tapped out
vent will be the oil fill . These are proven transmissions that are user friendly and can handle all the horse power you can throw at them.
The Porsche 997 is for left hand drive . Call me at 321-292-9005 on Whatsap
