By re-popped, I meant that they have not been reproduced in the aftermarket. Also, the caps for '61 and 62 were only used those 2 years. The '60 used the same caps as '57-'59, and the '63-'66 are the same. There just hasn't been enough demand in the aftermarket yet for them to do the '61-'62 cap, yet. I will point out, though, that there have been other 1 or 2 year only caps done in the past, like the '54-'55.1 and the '55.2-'56, but that is due to demand.
