I have a 1963 GMC 4000 truck that I need to replace the torn floor mat. LMC (and others) show floor mats for pickups, a tall hump (for standard transmissions and 4wd) and low hump for automatics. Since my GMC 4000 has no hump, can I assume that the floorboard for the automatic pickup cabs will be the same as my truck cab, or is the pickup floor board still raised? Thanks in advance! JP
