I have a long stepside bed. It came to me dismantled and had the full length tool boxes instead of fenders. I realize the tool boxes are after market. I am trying to decipher what other models the front panel and tailgate would fit. I am assuming it is late 70s due to the duel fuel fillers. It is a low side bed and the tailgate measures about 55" by 21 3/4 "
any info would be appreciated. thanks
