I searched around and couldn't find any info about body compatibility from year to year. I've got a 96 geo tracker 2door soft top with a mangled drivers door. Can anyone tell me what model years for trakers/sidekicks I can salvage a door from?  Could I use a front door off a 4 door?  And any idea what I can expect to pay for the door?

Thanks for any info

No, you need one from a 2 door as they are longer.

Thanks. I figured that was likely. Any idea if all the 2door tracker/sidekicks from 89 through 98 used the same door?

You can swap between any of the Trackers/Sidekicks around those years.  Not sure about the Sports though.
