A pair of Hot Wheels '83 Chevy Silverado - Mainline editions

I've been on a pick-up and SUV tear as I try to organize the collections, so I decided to showcase this pair of 1983 Silverados. Would have preferred a more stock version, but this custom job looks pretty good. I think it may have come with a plastic insert for the rear wheel covering, but am not sure. I've seen versions where it's missing when still in the pack, but I thought Hot Wheels did make a piece to cover the axle (as seen in the Friday Night Lights 4X4 version).

With the Silverado 4X4 in the center, the trio of this casting I own.
