Congrats, yes! another 289! . I'm filling/block sanding mine as we speak. I went with a Wilwood external slave for the clutch, I didn't want to have to pull the trans for any issues. Works great from the little I've driven it. If driven hard, the splines on those wire wheels and the spline hub themselves will wear to a knife edge, and can shear. If driven normally, they'll be ok.
Enjoy the build!
