manual steering box coupler,rag joint

Technically, the coupler is not a "rag joint". It is sometimes referred to as a "Plunge Pot". There is no fabric in the unit as there is with GM style couplers. You will find rag joints in some Mopars though....Starting in around 1975 or so, Chrysler sourced steering columns from the GM Saginaw division when the T I L T wheel was ordered.
Good luck with the car.
