Bushing on shaft under mechanical advance?
From the looks of the shaft, a bushing kit would probably have done you no good, anyhow.
Don't toss the weights and parts, a few of us, crackedback, even me, might use em. You can weld up the slots and use 'em for a "recurve" What's the thing stamped on the bottom, a number? That would be the advance
This one is 15, that is distributor degrees, so that's 30 at the crank, a long, slow "smog" distributor
