Little off topic but a true memory with regards to the ‘67 tach. Shortly after I bought my ‘67 GT 500 my mom and I we’re heading from SF to Seattle Washington. Was moving along quite well when my mom says “seems like we are going faster than r-mph”! She was looking at the tach, not the speedometer on the left! Shortly after….near Redding….got pulled over by CHP….not for speeding but because my inboard high beams were to bright! Ah, found memories!
