My 76 F250 4x4 has rubber mat on the front half of the cab and red carpet on the back half of the cab under and behind the seat. Was this factory? The mat and carpet need replaced and everything I am seeing is either a full rubber mat or full carpet.

 

sounds like the front carpet was bad someone did not want to go to the trouble of removing the seat cut out the bad and put in a rubber mat. Definitly not factory.
