What is unique to F100 4x4's?

[farmtruckman]

Am looking at a '70 F100 4x4 sometime next week and am looking for what is unique to the 4X4's. I know the VIN is "F11" for that year. Someone told me that the 4X4's came with a box frame verses the "C" channel on the 2x4's. Anything else? What transfer case came in the stock 390 mating?

Any help or suggestions is greatly appreciated.

I'm pretty sure they did not come with the 390 . Doug

Yes the did not come stock with a 390, he 360 was as big as you could get. It most likely has a NP435 married to a DANA 21 T-case. They are coil sprung up front instead of leafs like the F-250's and larger. I know my frame is a C channel except a few areas up front where the steering box an motor mounts are. Those areas are boxed. The F-100 4x4's sit a little lower than the F-250's. Thats about all I can think about.
