Feather duster value

I just learned something new too. I didn't know that there was no V8 in them either. I am not in to the 73 up cars because the bumpers hurt the looks to much. 72 is the last year for the 8 3/4 in the A-bodies.
lol i tried taking the bumper gaurds off ,it didnt help much. i really wanted an earlier duster but had to settle...so did all feather dusters and dart lites come with a small bolt pattern as well or had they changed them all to BBP by 76 ?
