Dan,
Wow, sorry to hear that. Yes, I have or can get (from McMaster) the parts. However, if the teeth on the jackshaft are worn away/broken then new seals are not going to help.
What are the symptoms at this point? Does it "just" leak (which would be good at this point) or does it overheat shortly after being started (indicating that the pump is not turning)?
I'm a little unsure on yours as a '76 should have originally had the steel gears, so unless the motor was replaced with a later one they gear teeth should be pretty robust.
In '77 and later, if one replaces the whole pump instead of just the impeller and seals, they may have made the classic mistake of using a new pump shaft with an old jackshaft which almost always is a bad idea. I can imagine that it would also be bad to put a cast iron pump gear with a steel jackshaft gear, but I'm not sure if that's possible.
My personal opinion is that I don't like the electric pump solution as it requires quite a bit of modification, but I can understand the reality of the cost of pulling out the engine and replacing the jackshaft. The only caveat on that is that if the jackshaft teeth did break then there are a bunch of little pieces of metal in the oil pan, so it might not be a bad idea to take it out and make sure that's cleaned up.
I don't have any personal experience doing an electric pump - you would have to block off the holes in the block where the shaft/bearings go in order to keep the oil where it belongs and the coolant where that belongs.
If you are not sure the exact problem and want to put your shop in touch with me directly I'll try to help - contact me off line.
Best,
Gary
