Thanks for the explanation and the tip with parking. Good tip on the safety side.:-) I will look at the drivers side visor(hope the truck has one)once the truck arrives. how i interpret what i have been told is the low/high control for the 2 speeed rear axle is located on the dash. w/o a load keep control in the high position with normal shift throught the 4 gears. When loaded, start in the low control position, clutch into first gear, then change into the high control position while in first gear w/o the clutch; clutch, change back to low position then shift to second gear, repeating this pattern through the gears. do you switch from low to high position with or w/o the clutch? I purchased a 1954 "truck data book, specifications catalog for chevrolet salesmen" from BowTie Bits and it shows the std. shift pattern (H) but no explanation when using the low/high 2 speed control when shifting gears. Sounds pretty elementry but when you don't know it is monumental.
