I found a truck with a working gauge that the face looks like crap but the movement and most of all the coils are good in. I may be a glution for punishment but not just looking for trouble. I figure that I can spend the time on the front disk conversion, dual master cylinder or maybe the rear end. Oh! wait or the million other things this truck needs. Thanks for all of the info and I did save the wire gauge chart, just incase. Someone had a great photo site of a rebuild of a stock A.D. radio vibrator, lost the link when the computer crashed. Ringing any bells?

Thanks again
Neil
