Really nice 3921s date code D5 carb for a 65GS 401 automatic. I completely disassembled, bead blasted everything, painted the steel parts, and assembled it with a fresh rebuild kit. This one has the nicest base on it of any I have ever seen. Most are pitted where someone omitted the Stainless Steel plate that goes between the carb and intake. $320. Includes shipping in a USPS large flat rate box from Mocksville, NC.
