Mr KaiserFrazerLibrary <g> answered that one in another thread--the *-* with a number behind stands for folding or non-folding read seat. He didn't spell out which was which, but if the trim code is 4424-2 and your seat is folding or non-folding, then you know what the -2 stands for, and the -1 would be the other type. According to him, the factory needed to know which type it was in case a replacement seat was ordered, as the upholstery/trim was attached differently depending on whether it was a folding or non-folding seat.
