OK, so I know there are a lot of threads out there about this and I have been reading them. I don't mean to beat a dead horse here but I do have a situation I haven't found an answer to. I have a cab and chassis 96 f450 I believe. The fender tag only says f-series. I got the truck from my wife's uncle who bought it in Chicago off the lot in 96, he says he thinks it was an f450 now he and I could both be wrong maybe it's a f350. Either way he took it and had a dump bed put on it. So here's my question, with it being a cab and chassis I already have leaf springs in the front. I know that a cab and chassis was the only way to get a 4x4 back then and obviously mine is 2wd. I should mention that its a dually as well. So with this truck being a cab and chassis would a swap be easier? I know I'll need a new trans and that's fine. I think the trans in it now is giving up and thats were the idea to make it 4x4 came from. Also I thought I read somewhere that the cab and chassis rear ends are narrower? If this is true would I have to get a front axle out of another cab and chassis? I would imagine my shock towers and leaf springs would work with the swap and i shouldn't have to do the conversion to the frame. Let me know what you guys think. I'm trying to get a head start as this will hopefully be one of my winter projects after I get my shop done, and the motor back in my jeep.
