Hello, usually they will be different sizes or angles in order to accommodate for the oblong shape of the window glass and door. To be completely sure I would use the aftermarket part number to make sure it is supposed to fit your vehicle.

Hi William, reason i ask is regulator failed, on inspection i found a very new regulator but the cable snapped one of the sladers, and also noticed both sliders were identical of each other, looking on line i found all the listed ones look to have 2 sliders but not identical can you display a picture of the (2) sliders that belong on my 2003? I'd like to replace just the slider if possible (Note) mine take the early style with studs.
thanks

This would be the left side regulator for that Caravan. Part # 5170941AA They may be a bit different in terms of colors of plastic, but the rest would be the same, the right side is a mirror image. If your motor is OK you can get just the frame assembly and swap your motor onto it, but those are commonly more money than a complete power assembly. You won't however find individual pieces because of the way they are assembled and timed.
