Gentlemen, thanks so much for your kind offers and leads. After my first knee-jerk reaction of screaming for HELP on this forum, I drove and called around here in town and finally found a guy who will rebuild it!
After getting the eyes-rolled-look , from 4 shops with guys under the age of say---half a century, I finally followed a couple of leads to a fellow to a junky-looking old auto and truck yard accross town. He took one look at the thing, took a suck on his nasty cigar, grabbed it, checked the play in the shaft with his huge fingers, looked me straight in the eye and said "Case?"
I nodded, and he said "yeah, I think I got a bin of these springs and weights, I should be able to fix you up in a day or two." Eureka! They're still out there.
If it don't work out, I won't hesitate to give you guys a call...slim
