I agree with 68 formula s, 150 speedo was an option. My 69 has or should I say had the 120 speedo, I put the 150 in it. It had no tach, but hopefully will. Mine had drum brakes as well, but am swapping to the sbp 4 piston disc. It also has the 4spd console, and console was a seperate option, not part of the A53 pkg.
