The inner door panels were rusted through, so I bought new panels from LMC. The new panels came with holes for armrests, so I bought replacement armrests. After installing, the seat back doesn't have enough clearance to rotate forward, hitting on the new armrests. I've looked in the shop manual and there is not one reference to the armrests. I have the original seat. Did these trucks originally come with armrests? Anyone have this problem?
