Hi - I have my underbed spare tire assembly and spare tire all ready and put on the truck, but it seems I'm missing a piece. From some literature I can see there was a steer-horn piece that went in the rim and fastened the tire down to the sliding strap with a wing nut I'm assuming. Can anyone take a pic of their carrier to give me an idea of what it looked like? I think it's probably a piece I'll have to make
