Just re-zinc'ed the original alternator pulley and fan. Turned out pretty nice, just needs a tad more brushing up.
If anyone wants to do it, I found it's possible to buy a new, or rebuilt alternator for a 68 and then swap all the parts into your original cases. Rotor, stator, bearings, brushes, diodes etc. all swap over no problem. Case diodes, condenser and bearings have to be pressed out. I used a small press, could probably be done in a vise. Front bearing is different, a modern sealed type, but fits perfectly, rear bearing is very similar but has a built in seal so the separate seal is not needed. The plugs and terminals have a slightly different scheme for insulation, but it doesn't show on the outside, or old terminals can be reused if desired.
When I get the pulley and fan installed I'll take it down to NAPA and have them test it. Considering a new rebuilt alternator is only around $50-60, it seems like a good way to end up with a rebuild unit with the proper dated cases. Well, assuming it tests ok.
Used the old fan and pulley because the new types are noticeably different.
