I was shocked at how many parts were still available from Ford on my 1994 Explorer and 1994 Ranger. Radius arms (cheaper than aftermarket too), air intake ducts, all kinds of switches and things, etc. 1994 was the last year many of the parts I bought had been used in a new vehicle, but I was buying them from a local Ford dealer in 2015-2020, and with recent production dates on the packaging. I suspect the air intake ducts were available entirely due to the number of these trucks still running around in CA.
But the ballast for my stupid neon brake light in the 97? Nahhhh...who needs to fix their overly complicated high mount stop light?
