[bilgerat]

Picked up a 1 owner 79 GMC 2500 van with a 400sb and turbo 350 tranny today, has 142k original miles and the tranny was rebuilt last year, she was ordered with a heavy duty towing package to pull a 27 ft bayliner from North Ga to the Ga coast twice a year but only made 4 round trips then they sold the boat, been used as a 2nd family car for the past 20 years. I paid 1400 bucks for it! this thing is a beast!
