So now we have 614 325 and 312 , feckin part numbers.
I see the same thing in rally gauges from 67 to 72. Lots of part number differences that really dont mean squat in the fit, finish, function, of the part.
I run in to that all the time. There is like 6 part numbers for the AC control switch on the AC cars but the switch looks, appears and functions the same. Got to love MaMopar.
