I have 2 rear trunk lights in my collection

I'm guessing one is from the 72 shell that became a race car
but not sure which year the other is from?

the significant difference being the direction of one of the connectors

who knows which is from which year?

Looks to me that the tab was simply unfolded

crap... I think your right
I didn't see that before
maybe there is no early - late

I'll try bending it back tonight
thank you
