I have an interesting, and possibly boring thing I noticed on the Tech Tips. Item 7, Shifter & Parking Brake. (First let me make it clear, I appreciate the work to put together this Advance Design Overview!)
I am not sure what year 3/4 and 1-tons got the foot actuated parking brake. My first 1950 3600 I bought in 1999 had the hand actuated parking brake and no pedal. My second 1950 3600 I bought in 2003 had the pedal. I think the 1999 was built in April (D) and the 2003 built in July (G), if I remember correctly. Do you think there were rolling changes not fully documented? What do others have in their trucks? Was mine with the hand brake a fluke?
