I'm NO expert by any means. In fact, I'm trying to decode my '69RR. I have the same numbers on your last row. The way I read it is the E63 is a 383ci 335Hp; D21 is for four speed; RM23 is for HARD TOP, mine is RM21 for the COUPE; H9G is for 383ci, 1969 year, G plant. Mine is E for Los Angeles.What is M21 code next to END on my tag. I have the window sticker and it’s not on it.
I find the fender tag not very accurate as it doesn’t list power steering, tinted windshield,undercoating,sure grip, and a couple other things.
Makes me wonder what’s the big fuss over fender tags. Car is a 69 RR.View attachment 37113
