My 1968 1/2 4X4 frankintruck I’m trying to get going…

[custom10nut]

Gummed up Shifter rods was the main reason that I bought a tilt unit for my truck.
After I tore the original apart, I found all the gunk, grease, and dirt that had accumulated in 50+ years.
If you take the steering wheel and hub off, you can spray some cleaner on the internal parts of the shifter, and working it back and forth, you should be able to get get it freed up.
This is only a temporary fix though, as all that gunk will just be softened up, and the problem will eventually return.
The true fix is to disassemble the column and clean it.
