I recently got a roller chassis for a 1979 F-350 standrad cab long bed for free, no engine, no tranny, no cab or bed, just a front end and rear end, only problem is it's a 2WD, can I swap the front for a 4WD front and can anyone offer and advice suggestions etc. my plans will eventually include a 351 modified to a 400 and roughly 9" of lift for 38" tires......thanks in advance
