Change my mind:

I think I want to keep the generator, and actually I'd like to have the original one rebuilt. I do want to keep the set up as close to original as I can. I'm not looking for high performance or latest and greatest. I'm not really concerned with the price either way. I think I can get a new/rebuilt DELCO generator for like $350, so that's not too steep if rebuilding the original is in that ballpark. I do want it to run and be reliable, so that's the more important factor.
I value all your opinions so thanks in advance.
