Mark,

I have the original shaft but believe it to be to long. I have found a few in the local yards while hunting other parts, but most were way to rusty and my original is in good shape. There is a good local shop that will shorten and balance for $50. Should have the new rear finished this week, so I will install it and measure per the suggestions. I found a post in a Nova web site says it should be 51 1/2. We'll see.

Thanks for all the suggestions guys.
