I have a 84 single cab longbed 2wd, and found a guy on craigslist selling parts from an 85 4x4. I was wondering if the parts list in his post would be everything that I would need to do the conversion. And also if it was do able to just swap them out, or would it be major modification. Here is his post.

"Make your Ford F150 2wd w/ twin I beam suspension into a 4x4. It will work on a 300 6cyl, 302, or a 351w. Everything you need-front differential, c-6 auto trans and transfer case, rear end (to keep correct ratios),drive shafts, lock out hubs, complete drive trane out of a 1985. Bolt it up and go. $500.00"

Any help would be greatly appreciated. Thanks

 

Don't know for sure about the parts needed? He did not mention suspension parts and I know they are different 4x4 vs 4x2
It seems that every time this question comes up the consensus is that it is cheaper, easier and better to just buy a 4x4 truck.
