Hi everybody! So my wife convinced me to buy this 1985 k20 from her dad that he found sitting in a near by field. I know not much about mechanical things but this truck got me learning quickly so far! After sitting for almost a decade it just needed a battery, a slave cylinder, air in the tires and some gas. The 4x4 works flawlessly! It drove the 90 min trip home just fine! All I know is it's a 350sbc, sm465 tranny, and I don't know about transfer case, I think the paperwork I found says it has 3:73 gears in the rear???? Either way I'm in love and it was only $600!!!!
