my 64 greenbrier has what appears to be an unmolested dash. it shows 100 mph with no shift points. it was originally a 4 spd. i changed it to powerslide. the earlier fc's ive had all had shift points on the speedo wheather they were 4 spd, 3 spd or pg. i think i read somewhere about the change in 64?? i usually try to put spyder dash in anyhow... regards tim colson ..... liking his trip odometer...
