Thank you Phak1, Guitplayer, Cmayna and Hotrod Lincoln for all of your valued advice. This posting has taken some different twists from what I was originally seeking, but at the same time has turned out to be a big help in any case.

For clarification, (1) I cut the old bracket down and welded the shortened pieces together for a brace for the new alternator to set in and then (2) cut a plate the same thickness as the old generator mount brace, (3) slotted the holes for adjustment for mounting on the engine block and then (4) welded the brace in operation #1 to the new plate in operation #2. It all fits and aligns. It's just a matter of getting the engine mounts bolted on the right side and over the aforementioned plate on the driver's side. The original adjusting bracket for the top of the generator isn't long enough for the new alternator so I'm going to have to weld on a extension for it to attach to the bolt on the water pump. I hope all this is doesn't fuel more confusion.

I'll send a pic of it first of next week when I get back out to work on it. Again, thanks. See you next week. Have a great weekend and try to stay cool.
