My c4 transmission went out in the cougar, has no forward. So I have decided to do a 4r70w swap. I have found a transmission locally with 22Kmiles for 475.00. Parts I have acquired are a slip yoke from 98 crown vic, us shift controller for the trans, acculink tps kit for carburetor, and transmission crosmember kit from Joe Persad from the all ford mustang forum. The flex plate that is needed for this conversion 164 tooth 28oz.
I have seen double ring gear,single ring gear flex plates,sfi and non sfi flex plates. I think that a sfi flex plate is not needed because the car is not for the drag strip. I do not want to buy a cheep flex plate. Any Info on a good flex plate would be appreciated. Sorry for the long paragraph.
Thanks Scott
