Mech. Speedometer Cable?

[dstryr]

Well after some searching I found that summit sells an adapter to change the original speedometer cable from clip on (71 Camaro) to screw on....but my real question is.... is there any other options? The little adapter is 50 bucks and Im not sure if the old cable still works.

this is on a 71 with a m20 4 speed.



Thanks,
Dennis
