Yea it is a rare one. All original father/son owned 83 half ton reg cab 2wd with a 305 that sat in a field for about 5-6 years at least. Only has 60k on it. I talked the old guy into letting me take it off his hands. I washed it off, did the necessary belts, hoses, carb cleaning etc.. that a smart person would do and fired her up. A little tuning and it hasn't missed a beat yet besides the starter going out. It looks like hell but runs like a dream.
