Thanks for the fast response on the 14's ! Another question regarding pace cars. Is there supposed to be a yellow crayon marking on the rear bulkhead indicating an "X" code. I have seen the "X-7" and "X-3" markings on Z-28's on the passenger side rear seat bulkhead. Have been told that Pace cars should have a "X-0". Does anybody know if this is true? Also being that bulkheads are different from convertibles to coupes would the supposed "X" marking be in the same general area?
