I just picked this up yesterday in trade. I am not quite sure what to do with it yet. The engine and tranny are in pieces in the bed, so keeping it stock is kind of out the window. I was thinking about putting my favorite light truck engine of all time, the Ford 300 straight 6, in there. After measuring and looking for engines I noticed that the 73-79 f100 has roughly the same wheelbase and track width of the IH, so now I am thinking a full frame swap with a swb F100 that already has the 6 in it. Then I'll have my favorite truck engine with my favorite truck platform, but with this unique body on it. And since this Binder needs pretty much everything anyway, it seems like this might be a better option. It will give me the more modern and reliable stuff I want and I can actually get parts for it anywhere. Anyone see a problem with this plan or have a better suggestion?
