Can I change vent window assembly from 70's to late 80's suburban?

I have a 1987 chevy, it's a hodge podge of different trucks. I know it has some front doors from a 70's crew cab. I tried to do vent window seals, but I've tried the one piece and the two piece seals, neither of them want to fit. Fed up, found a set of 88 suburban vent window assemblies and would like to know if they will work with the window track in the old doors.

IIRC, it would be better to get the whole door from the 88. There are subtle differences in the body of the doors, i.e. power windows started in 77 or 78, and there have been 3 different types of wing windows.

I have done some research, the screw holes look about the same, but I am worried about the window track part of the frame. Would that have changed shape through the years? Doors I have recently found are from a '74.
