The connectors might be different, but even if they are, you can simply swap them if you don't want to cut/splice wires. Some aftermarket motors even come with several different wire and plug combos to fit lots of different model years, and you just plug in the one you need.
Looking at the motors even more, it seems the housings aren't different, the only difference between front and rear seems to be the gear that drives the regulator. The front has a 9-tooth star-shaped gear, the rear has a 6-tooth hex/spline-shaped gear.
My guess would be a front motor would work on the rear and a rear motor would work on the front if that gear was swapped out for the correct one. The housing on the front has threaded holes to mount to regulator, and the back are through holes. All of the guts in the housing can be switched out to use in any door. You can even separate the motor housing from the gear housing and reuse it, just pay attention to the brushes.
