got the new clutch for the car. It is a quarter master twin plate. They messed up when they made all the fly wheels to start with. They used a 6bolt crank only to make the aliment rings on the flys then just put in 6bolt or 7bolt holes. The 7bolt crank is bigger so the fly wheels do not fit at all. Other people have the same problem sense they got theres yesterday one in OH and one in the UK all 3 of us were not happy at all about this. The diffrence in the cranks is. the 6bolt one is 3.134in. and the 7bolt crank one is 3.345in. Lucky for me my Dad's buddy has a huge laythe that will hold the fly wheel and my Dad turned it out so the fly will fit the 7bolt crank like it should have to start with.
