Most aftermarket step bumpers have the bumper brackets welded on. Ford step bumper brackets bolt on and are "weak sisters." A slight tap on the bumper causes it to sag downwards like an old swaybacked nag.

September 1987, was driving towards Mount Rushmore. When I reached the Needles, I spotted something I had never seen before, was totally unaware of: 1965 F250 Crew Cab Styleside parked alongside the road.

I stopped, got out, took a few pictures, still have them. March 1965, bought a new 1965 F100 8' Styleside, but was not aware of any Crew Cab version until 22 years later.

WOW!! You have quite a collection. Next time you're in Twisp, check out the 1956 Ford COE wrecker parked next to a repair shop. I shoulda stopped, taken a few pics.

There's a "one lung" engine museum in Vista CA
