1-C7ZB-6504371-A
What is the other number ?
The other delete plate engineering number is C7ZB-6504371-
BNot sure why they are both 67 numbers, as I've only seen the "B" plate on 68's
The only difference is the lower chrome edge is rounded off instead of having square edges like the earlier plate.
I can post pic's of both if that will help.
I'm guessing that the change came about with all the other safety related changes in the 68 interior.
Hope this helps, John
