1971 RR and Duster 340 Master Cyl Correct one???

Can anyone tell me the correct Master Cylinder part numbers for a 1971 RR and a 1971 Duster 340 Both are non power drum brake cars... Also, could someone post pictures as well? TIA

Anyone ?

Usually there are great "numbers guys" on here that chime in to this stuff. Some of the stuff known is truly fantastic! There are possible earlier threads dealing with this. Did you try a search through the past MC threads?

Here is the typical 71-up master, Inline Tube sells is, and it seems to be the only one that Cardone sells at all auto parts stores for every Mopar ever made disc brakes and drums...
