Greg & Josh,
I do not know if this is information pertinent to your discussion: the 1954 Truck Restoration Packet "Chevrolet 21954 Specifications" lists as an accessory: rectangular floor mats, choice of 5 colors. This was a GM dealer accessory that was available for all model 1954 trucks (this publication is dated 5-1-54).
It looks like these mats were not in the Deluxe Cab Equipment package (RPO 430/431); but, they were available as a GM accessory.
