Thanks Fred, Bill, and everybody - I think I have the path now and your know how has really helped a lot. I'm not sure if I'll tackle rebuilding the speedo or replace, but now I can get into it and see what might work. I have located a few replacements, both reproduction and used originals so I know they are out there in case I screw it up. I'd like to keep the odometer if I can. I am really pleased with the response from all of you and have picked up 10 times more info this way than the books I've bought recently and my own experimenting. I'll get back if I have trouble with it -I'll get back either way -- thanks again guys Dale
