tjc transport Posted February 19, 2019 Share Posted February 19, 2019 i remember the old bossman taking me to Glasofer Mack in Edison NJ to pick up one of them. it had 9 miles on it when i left the back lot. it had a little over 650,000 miles on it when i moved on in 95. great truck. 300hp with the "mud stick" and 58k rears. only thing wrong with it was the top speed of 52 MPH.
