Really!? LOL, no chit! I didn't know that. LOL, leaned something today. Dang!
Mopar ta ya, $50 isn't to bad if it is basically un-rusted, a minor amount is OK, it happens, the crud level is low, not a greasy messy thing, operates freely, twist open the throttle plates and see. No gas sitting in it for months on end would be a big plus.
If it looks really good and you know or trust the seller with him saying it is a good carb, then no more than $100. I don't care what e-bay sell's them for. It's gotta be a real NOS part or seriously sweet for me to even think about going over a benji. ($100) I have shelf full of $20 TQ's.
