67 Barracuda Speedometer Questions

I would think that a 1968, 150mph would fit a 1967. All 150mph speedo's had tripometer, some 120mph did also. To add to the confusion, I have owned two 1968 cuds's, late '68, and both of them had screw-on cables. If one wants a 150mph speedo, any should work. Make sure you get the knob with it.
