Hi Gene why don't u ccome up for a drive to my place and blow the cobwebs out of your Torana Gene. The wifes Sandman Van is 63 v trim while it is worn its still pretty much original. Two tone dash painted console etc but pretty much untouched. My understanding is that the 63v buckskin is the early to mid HZ code for buckskin and 63c is on the late model HZs and coincides with 63c as found in the first commodores VB. Maybe find a commodore with 63c and compare? If I get a chance I will give Reg at Muscle Car Motor Trimmers a call he is bound to know.

Pm me for address if interested Gene

Cheers Dave
