Update: Looking for a new/rebuilt carburetor. 1985 Chevy c10 5.0L 4spd VIN 1GCDC14HFS188### (wasn't sure if posting a full VIN was a bad idea). I received a Haynes Manual with the truck and it lists M4ME,M4MC as possible carbs. When I look at NAPA they have 4 different carbs. Then looking at National Carburetor they only have 2 Part# ND4478 and ND4484. Just looking for a little insight. The National ones are cheaper and from a couple posts on this forum seem legitimate. Any help on this would be greatly appreciated. Thanks
Also, if anyone has any questions on lobster fishing or fiberglass/composites those are my areas of knowledge.
