Just bought a 75 sierra. 4x4 question, looking at the shifter I take it being in “n” is two wheel drive, up for 4x4 low and down for 4x4 hi? Then lock front hubs in hi or low for true 4x4? And how can you tell which your in at any given time. Like I haven’t touched it since I bought because I’m not sure and don’t want to break anything. Lol.
