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.

Leave the rear end as is, yes the rear frame rails are narrower. Find a dana 60 front axle and the dually conversion spacers, or dually front axle, 4x4 transmission, transfer case, and driveshafts and your good to go.

Is there anywhere I can buy the dually spacers? Or what year front dually axle would work with my truck?

Google dually spacers, buy the steel units. They arent very cheap so dont he shocked when you cant find steel units for less than $400.

80 thru 97. IIRC up to 91 will be king pin, 92-97 will be ball joint. Keep a eye on eBay and craigs list, conversion adapters show up occasionally

I honestly don't know if it will even bolt under the truck. The lug pattern is different from an obs pattern so different rims are needed
