Sorry, I meant the bottom bumper appears to have front brackets I'm used to seeing, they also measure 28inches apart and the other one measure at roughly 44 inches apart...so forure will bolt up to a 35-41 pickup chassis...
I've been looking at ebay trucks, appear to match up to '39's...probably others too...ya, they'll work for me...little sanding and paint and by golly I'll be in business!
