hello everybody. my screen name says it all. i'm the very proud owner of a new to me '97 F-350 2wd 5-speed with the 7.3 turbo diesel. i got the truck at such a good deal that i could not pass it up. i would of preffered a 4wd F-350 instead but oh well. now this is where my first of many many questions come in. how hard would it be to convert my 2wd to 4wd and how involved is it? is it worth the time and money? i imagine that this has been done before so can somebody please point me in the right direction? thanks for your help now and in the near future.
