The easiest method that I am aware of is to source them from any shop selling Reese hitch products. Most Vintage Airstreams need what is sold as U-bolts for 4" and 5" frames . . . these usually need to be ordered as I have yet to find a dealer other than one who does business with Vintage Airstream owners that actually stocks anything other than the larger U-bolts that are utilized on Brand-X as well as late model Airstreams. I keep an extra set of 4 in my parts kit as I generally replace them every time that I repaint the hitch on either of my coaches.
Good luck with your investigation!
P.S.: This link has the U-bolts that I utilize with my Vintage Airstream and Argosy . . . Link
