Yes, probably from the "acid bath". Holley also "tumbles" the airhorns, and the fuel nozzles are almost always bent and mangled up as well, driven in too far, etc. I HATE so see any remanufactured units coming in here, especially those from Holley.
I suspect they farmed that work out South of the Border someplace. I'd hate to admit that an American Company did such crappy work then put their label on it......Cliff
