Hi Denney...
Enjoyed your story about retrieving your truck from Kansas. It does have that natural outdoor weathered look to it, but as long as the sheet metal is solid you've got something to work with. This type of truck is notorious for rotten cab corners and quarter fenders. Yours appears to be quite solid.
As far as the transmission shift pattern goes the forward gears are the standard 'H' pattern with upper left as deep low, straight down is 1, upper right is two, down right is high. Believe me it'll seem like you should have one more higher gear but you don't. These trucks are slow, at 50 MPH the motor is turning wide open. Reverse gear should be spring loaded with the position at far left and down (close to your leg). At least that's the pattern on my '57 dump.
Good luck with your new find, keep us posted!
James
