Most of the steering column weight should be supported by the brake / clutch pedal bracket so not sure how much weight would really be on the dash frame.
Plaza made some really nice well built unique parts for the time probably a lot better than anything made today.
They seem to have made the glass parts from direct molds of the original steel parts as the are very exact in every detail including some of the number stampings that you would normally find in steel pieces.
The doors appear to been made from hard top molds & outside of the doors have raised bosses for the door handles along with the inside has everything to mount handles , regulators, panels & vent windows if you wanted if using them on a sedan or AFX you would have to add your window frames which took some slight massaging.
The trunk lid even had the raised reinforced hinge area if you wanted to use the factory trunk hinges along with Dodge raised trunk medallion area . It would be interesting to see a old catalog since I'm betting the hoods where sold with or without scoop mine shows no sign of ever having a scoop attached & I've seen a few other hoods that way.
