Interesting info given. I will be doing the same thing soon. Please PM me any really useful info you get. I'll do the same. I read a thread somewhere where Jim W. did this and I think (trying to remember) he said like 72 Electra frame mounts lined up with 2 of the 3 holes in the frame. Isn't that nice (hope my info is correct, I teach middle school science, and spending every day 13 year old kids make me 10 times dumber than the day before)?
