Actually the 1 7/8” is the long one Joe. The short one was used with the 261 and V8’s and is 1 9/32”. As far as I know there was never a 2” throw out bearing used with any Stovebolt. Once again, this is pretty straight forward, only two choices to make your selection from if it’s GM Chevrolet parts your talking about.
