For sale is a 70-72 tachometer that i'm told is correct for 71 or 72, but will work in a 70 as well....not sure,so please do your homework. It came in a package of NOS parts that i got recently as was supposed to be NOS, but it's not. It looks to have been mounted in a car previously as you can see where a nut was tightened up on the flanges. Overall condition looks to be very good, but I can't say for certain whether it works or not. I don't easily have a car i can try it in.....everything is put up for Winter! The part number on the back of the tach body is 5657334..I'd like $250 for it shipped to your door via USPS with payment by USPS postal money order. Carl U. has first crack at it, as he posted interest on it in the "wanted" section, than Dennis-YNOTNBUICK is up after him....Thanks! Chris
