I usually dont see many of these around for sale, so I thought I would ask here about them. Buick OEM Indash Tachometers for '70-72?(not sure what years were the same) Cars. I've been looking for one for my GS(although not a high priority for me right now) and I was either going to go with a OEM Tach for my car or put a Sun Super Tach III in the Dash. Depends on the price I guess. So, can anyone here tell me how much they usually go for if you can find them for sale?
