1958 Plymouth 318 – four barrel rebuild kit??

My car runs ok but been thinking I should rebuild the carb. Most shops around me charge $275 and up for that service and I've done a few rebuilds in the past and not hard. My question is, does anyone know where to buy a rebuild kit for the factory Carter/AFB 4 barrel carb that came on the 318 in 1958? Tried looking at some of the numbers on the carb but just not sure.

Thanks in advance.
