Stop in for a cup of coffee

Sold a 74 Duster passenger glass to a guy with a 73 for $10. Told him it probably won’t fit…. Anyone know if you can put w 74 regulator and glass in a 73 door? Or is the door different?
May have to drill some holes but it should physically fit, '73 stuff is all one year. I just left one side '73 and one '74. @dukeboy_318 has my old doors I believe still.
