I'm trying to help a friend so any info would be GREATLY APPRECIATED! The truck is a mid 80's Blazer with a manual tailgate. The outer window crank handle has broken off with the window in the down position. He has taken the inner access panel off to work on it but the glass is in the way. Of course, he wants to replace the handle, what's the best way to disassemble the tailgate. Does anybody have diagrams or anything? I searched but mostly came up with electric gate info. THANKS!!
