The 4x4's use a foreward front crossmember, several different steering arrangements, a rear sump 4x4/van oilpan. The f150 4x4 and all 2x frames are the same width. The leaf sprung 4x4's turn tighter but use a narrower frame than the older trucks and highboys that have different bodymounting holes than the 2x. and coil sprung 4x trucks.
What is it about the twin I Beam setup that makes it more difficult - that is, how are the 4x4 front ends different (aside from the obvious differences in axles, steering, etc.)?[/QUOTE]

Lets pretend i have a mid '70's F350 2wd 460 powered truck.
If I find a 4wd frame to use, it will probably not be a 4wd F350 frame because thy are hard to find.
If I use a F250 I can not have a 460, as 460's were not in F250's until the '80's. (At least none that can be proven to the IM referees) In that case I could use a newer 460 if I retained the all IM related parts.
Reworking a crossmember is trivial compared to that headache. I put a D60/and D70 under my Explorer, then worked it hard off road up here, so I have some actually wrench time to back up what I am saying.

There was a conversion done by 4wheel and offroad where they used a dodge front axle divorced transfercase and springs (because they were plentiful surplus)under a 2x, the lift was enough that the crossmember wasn't an issue.
