1956 Buick Clutch Replacement

[3spd]

Anyone know if other makes share the same clutch as a 1956 Buick with a 3spd Syncromesh? I know chevy's used the same number of splines and shaft diameter but I can't find if the bolt spacing on the pressure plate is the same.

Thanks,

According to Summit this will fit my car: http://www.summitracing.com/parts/ZZZ-30042/

But, I measured my clutch and it is 11" in diameter not 10.4". Will it still work?

Also if it does fit will it being a circle track clutch making driving it on the road difficult?

Thanks,
Ryland

I don't know if it will fit, but I would not run a zoom clutch on the street. I had one on a GTO I had years ago and the 69 Camaro my wife has has one in it and I don't think they are good for the street, but that is me.
