Have an extra C6ZF-C Autolite 4100 carb that Id like to trade for a nice clean OEM C6ZF-C unit. Mine is just a bit too nice to use on a running car and would like one to use. Perhaps someone who is collecting parts for an HP t-bred would be interested in trading. Will consider an OEM unit that is rebuilt or not, but must be complete and aluminum finish not blasted. Tag on my nos unit came as a square service tag and I traded it for an oem tag. I'd be happy to trade oem tags or keep our own tags.
