1969 383 roadrunner project build date code

[Kmart]

Date build code 22B which means 22 Nov 1968. Year one and clasic industries offer date coded fuel filters. If I order a set do I order a 69 November. Will it be date coded Nov 68. Very confused. Any help would be appreciated. This is going on a numbers matching car.This is OEM factory. Maybe I need replacement. ???
