Follow-up question the the one I posted earlier: The 1937 Plymouth engine I am putting into my 37 Dodge has a 9-1/4" clutch. The Dodge engine I am taking out has a 10" clutch. Do I use the 9-1/4", or put the Dodge flywheel on the Plymouth engine and use a 10" clutch? The flywheels measure the same, but obviously the clutch bolt holes are different. I am using the Plymouth engine w / the Dodge trans, but need to order a clutch package. Also, why the different sizes? Thanks.
