Thanks Chris, that's exactly what I was looking for. I did take the sprockets off and change the the cam seals. It was a good thing I did. When I went to loosen the intake sprocket, it wasn't torqued, but not loose yet. It did have some kind of thread locker on there, so it wasn't going to come apart, but it could have loosened up enough for the pin to come out of the slot and the valves to stop functioning. And even though there was no leakage with the old seals, I replaced them.
I cleaned up everything, gave the brackets and pulleys a coat of paint, and reassembled it all Saturday night. So much for that extra hour of sleep, I finished at 6 am and that's after the time change!
The shiny alternator is the original one rebuilt by our local shop, Adema Alternator in Coopersville. It was another good move to bring it in along with the 94 alternator I had in my parts trove in for service. It turned out that something wasn't quite right with the voltage regulator, so they tested the 94 and reused its regulator to rebuild mine.
All is well, no leaks, no wobbles or vibrations. I had to trim off almost 2" of the new lower radiator hose due to the excess length buckling at the lowest bend. The replacement front motor mount prooved to be the cure for the hoppy-jumpy clutch release I would get sometimes, for the last 30k! Mmm, smooth!
Thanks again to all who talked this retired body man off the ledge!
