Carburetor size Question

That’s the one thing I would never ever do is a GV-OD. Way to expensive. The OE units will work fine. Before I go to a GV, I’ll spend on something else. IDGA CRUD how’s trans it is.
Gear Vendors is about 45 minutes away from me. Drive right past them when I go to San Diego.
I have called them about return units or seconds/ blems but they said they don’t have anything like that so buying a new unit is what I would have to do.
