Holley 600 cfm vac secondaries

I've got a freshly rebuilt Holley 600 cfm vacuum secondary carb up for sale. Traded it for some other parts in the hopes that it might fix some carb tuning issues I was having, but ended up finding an EFI computer, so I'm going that route. I rebuilt the carb after I got it, but never even ended up running it as the linkage was hitting the top of my intake and I didn't have room to put a spacer in. It's a 80457 carb date code 1586. I'd like to get $125 OBO plus shipping from 66049.
