The way I understood it was the 5 is the year, but the 13 denotes series 1300 and 14 means half ton pick up. I could be wrong but in my Chevy book the 1314 is shown as a Canadian half ton.
Good luck in the show. Will that be on Saturday's show in Ladysmith or Sunday's at Mill Bay or Oak Bay? I won't be at either as I am flying over to Abbotsford for the air show.
