Replaced master cylinder in 2002.
The most dependable vehicle I have owned. It's a long wheel base pickup with no shell. Other than some minor body damage, it's in great shape.
The seat has a tear in it, but nothing too serious.
The exhaust needs to be replaced.
The engine has no leaks at all. At every oil change, it is always full.
The transmission has a very small leak at the rear main seal.
Probably my only complaint about this truck is that the gas tank is on the passenger side.
Unless you build a very thin cabinet, speakers behind the seat present a problem, forcing you to pull the seat up until the steering wheel is in your stomach.
It has the original rally rims that came with the truck in 1980, and the original size tires.
I have an 83 k20 silverado 4x4 it has no body damage perfectly straight no dents. lifted 6 inches 35" tires brush guard two tanks one on each side very convenient. no tears on seat brand new crate motor 350 from chevy dealer. new tranny 700r4 automatic overdrive. no leaks anywhere. 3/4 ton three inch exhaust from headers to flowmasters no cats. perfect interior. love this truck I get about 11-12 mph.
