Denny - my case and tailhousing numbers indicate its a late '65, with the speedo drive on the RH side. I was aware of the different gear od's, but the problem is that the machined area on the shaft appears to be 1/2" closer to the trans than it should be. I don't see on any lists where there is more than one 27 spline tailshaft. I'm taking it to a Lacey shop in the AM that said they have a Muncie "expert". Maybe the gear can be moved back a little without "falling off" of the machined part of the shaft. We'll see.

Jim - I don't see a Race World in the Oly phone book at hand. There is a Ray Wallace on S. Bay Rd. and I think I know where his shop is - an engine builder, right? I'll check it out.

Thanks, guys.
