I presume you're speaking of the hole where the speedo cable comes through the firewall. Not sure about A body cars, but on B body they use the same hole.

And here's an image for 1967. I feel safe saying it's the same because the cable part number is the same 66-67 with a Muncie.

Based on carls picture, i would guess if the floor pan/firewall is original, then there will be a dimple in that general area
