I've got records of the following later dated Endura Delete 68 GTO's
06A - 06D - 07B
All 3 of these were special paint/spring color = Carnival Red
Tininjun68 is your car a special paint color ?
a local guy here has a Solar Red/Endura Delete/ HO /4spd/ AC car built in either April or May.
Code 674 on BHC is the Delete - in case anyone needs a quick refresh.
i thought the delete number was much lower than 2,108 - but its been a while since i've read about it.
