Not going to be much help on the plates, but someone with a truck should answer up. Regarding the seats I would contact Julianos about it, bet they have an answer.

Yes, Virginia was one of them...They did have 2 plate states in 1957.
Sounds like if you run the antique tag on the the back that's all you need. That's what I did in Washington State for years (it's a two plate state as well). Never had an issue. As far as the seat belt goes, do the stock style lap belt and nix the shoulder belt idea. No sweat...Texas is a two plate state and recent court precedent has it that the plate in front MUST be on the bumper (not in the window, behind the grill etc). There is no stock front mount for a 57 3100 as in 57 there were no two plate states - and contrary to poular belief ther is no grace on this (except antique plates which don'r allow daily driving) now you can get the parts from dealers for most cars made after 72, but I am not too keen on drilling my pretty chrome original equip bumper - nor making a plate bracket that is not stock and authentic for shows. Any ideas on a removeable bracket that can be relied on not to leave the plate at the side of the road somewhere - yet still comes off easily at the show?
ALSO - SEATBELTS - Although exempt (state law requires wearing them if installed and defines installed as post 1972 year models or any vehicle in which there are factory mounts - or an adequately reinforced method of mounting. I am a believer in seat belts - The laps I can handle by welding a channel across the bottom of the pan, but the B pillar has no way to mount the shoulder - properly reinforced (can't get behind the sheet metal to install a plate). Any ideas here?
