Spotbiltxo, what klhansen suggested i also second there is very little clearance from the glass to the crank arms, and the glass will rattle against the round rivet hinges and leave marks on the glass. both windows on my truck are damaged in this manner, my channel supports are still in place, however even with just the guide channel felt completely rotted away missing the glass moves enough to hit the assembly and rattle a deep scratched path in the glass over the years. photos attached, i think i know which rivet in Miraclepieco's photo is responsible too (the mirrored driver side of coarse). -s
