...and don't forget... if you do the Alf clutch cable mod, you can 86 the stand for the stock cable location, coming up off the top of the drive shaft, and replace it with a grease zerk. then it's ez to put in a bit of grease when it begins to make a bit of noise on down the road.
lol I too lost my original bucking bar that came with the basket-case mab when I first bought it... made one from a grade 8 5/16 bolt and it did not quite fit as good as I would have liked... sloppy in the hole through the shaft... and 8mm is only a couple thousandths fatter, which I'm running now.
I probably will cut one from a drill bit next time around. I'll try 21/64ths or 11/32nds. I think the ball is a standard .312 from any hardware store, IIRC.
