The original one in the dash,Goes no more than 160. the new mechanical sunpro sets at about 179 and works well.I cannot believe the help and info you guys can come up with ,most of the old timers around here are tight lipped about what they know and it takes a long time to get them to open up. Holy crap i guess I am a old timer cause i have been bustin my knuckles since 1969. THANKS for the info!
