I stopped today while taking my boys to a basketball game and asked about a 1979 supercab LWB 2WD a fella had sitting under tree in his yard. the windows are molded over and it has its share of bumps and dings. The bed has holes in it, but the cab appears to be in great shape. He bought the truck new and just bought another f150. He's telling me since it was the supercab, it was on an f250 chasis. He said the springs front and back are heavy. He is selling the truck at scrap price so I told him i would come get it wednesday. All the glass was good. I didn't look at the interior as it was locked and i was pressed to get to the game. Here's the deal. I've got a 69 Four Door that is on a f350 dually chasis that is 4 hours away. It is going to need a donar truck for front cap and a donor for chasis as i do not want a dually. I'm thinking of putting the 6BT and auto with OD from the dodge i have in it. It currently has a 300 with 4 speed on floor. Can i spring it heavy enough in the front to make the 6bt work????
