66 a- body 150mph speedo

Not sure but I have seen the 1966 150 speedo listed for 1967 also.

I do not believe that's true! I believe that the 66 has a larger outside diameter than the 67 and up rallye dash gauges!! I can check when I get home!

I have a cluster with the 150 speedo and tach for a 66 that's going into the convertible!
