what's a original 7 1/4 duster rear end worth

And don't misconstrue my answer. I'm not sayin it's a piece of ****. Heck, if you were local to me, I'd throw some money at you for it, or maybe we could trade something. I have a 7 1/4 under my Valiant and it's probably gonna stay there for a bit. So I would take another one.
