I sent an e-mail to KCMONGO on this. Is the easy solution to use the Vega disc recommended by Robert French in the Tech Tips? It seems to me that the problem is clutch disc travel. The measurements should be the same as the original transmission. It slides in without any hang ups to the bell housing and bolts right into place. This is on a 52 with a foot pedal starter so it has the original pre-53 flywheel. I am going to order one and check it out.
