The fly wheel is the stock flywheel that the car had when it had the 170 in it. 9 1/2. I supplied the number for the Bell housing. I’m hoping somebody can decipher that and let me know for sure if it is for a 65, 66 year application.
The bell housing is the correct stock one for a '65-6 slant 6 4 speed. If your driver's side mount is too thick, or, the passenger side too thin, or, the engine just might not be sitting straight, it could cause that misalignment.
