I am getting ready to install the cab back on my 63 GMC k10 4x4 truck and have a question about the cab mounts. Went to order a cab mount kit from LMC and they list one for 2wd truck and nothing for 4wd,Obsolete is the same way, Classic ind only list one and does not say 2 or 4wd. Does anyone know if there is a difference and if so what is it. ohwell
