What do you think they are worth? Why would someone want them? I get anything over what the guy is asking for them he wants $1200 on one and $1300 on the other. He says the diesel engine is worth $3000 pulled by it self. I have no idea but these mack's are in the $5000 range or more. I can't seem to find to many just like this one. One is a......74 GMC 1 Ton Flatbed Dually, 350 motor, auto turbo 400 tranny. The other is a........1985 Mack Truck Cabover Diesel, Box chassis, runs and drives. They both have clear titles and need battery's. Thank you!
