I believe the two doors of a 2 door are no differant than the front doors of a 4 door, regulator wise. I may be wrong but I bet NOT. I replace these all the time. Sometimes the side to side is the same part #, sometimes the front and rear are the same part #. sometimes all 4 are differant. Worth looking into tho. Just depends on the year and vehicle. I do alot of Chevy's and Ford's.
