The air conditioner doesn't work; of course not, it's a Chevy.
I had to buy a new filter; the old one was like a brick.
Burned out the clutch; replaced with one out of a bread truck, solid disk.
The seats are torn to the point that they would have to be replaced.
The odometre doesn't work, that's why there is no mileage listed, the gas gage has never worked right, the speedometre doesn't work, and I've had to wire in seperate gages to measure the voltage, temperature, and oil pressure.
The back brakes used to lock up if I barely touched the brake, and so I've just unhooked them, and I am relying on the front brakes.
All in all, a very dependable old beater. I use it as a work truck, and try to avoid the main roads as much as possible, as this truck is geared so low, that it only has a top speed of about 50mph at 4000 rpm. I'm afraid to take it much higher than that.
I've converted it to a standard transmission, and stuck on a four wheel drive front axle, and put locked differential in both axles, and even rigged up the transfer case, so that the front wheels turn a little bit faster than the back wheels, in four wheel drive. If anyone asks me what year it is, I just say, "Which part?"
To a lot of people, this may look like just an old beat-up Suburban, but to me, it's a Rolls-Royce in overalls... and mud-boots.
I doubt there is anything this truck won't tow, as long as it can get the traction. Just shovel some gravel into the back, and try again.
I wouldn't hesitate to drive it back and forth to work every day, but the gas-mileage is horrendous.
