Does anybody out there, know of a place that makes a Suburban Tailgate skin replacement.??? I gave up on changing to barn doors, so I'm just going to re-skin it. If possible. Also, how hard is it to change the electric window inards in the tailgate. My window innards let the window slip off and go up at a 45 degree angle. Then just as I'm about to grab the window, it slips and slides..no slams back down. How that window didn't break, I don't know. Thank you in advance for any help.
