I have a 2000 GMC Sierra 1500 slt 3 door. I do not like not having a third seat in the front and would like to swap out the center council with a jumper seat. Is it possible to do so?

not real sure what you meant but i believe the ones with the seat in the middle have different driver and passenger seats. you could go to a junk yard and check it out, you may have to replace it all, but the junk yard might give you some or all back if you trade your seats and console, its normally the more desirable set up
