F250 master cylinder

So I'm a moron and bought a master cylinder for a 4wd F250 (part #4739014) instead of a 2wd (part #7435408). So does anybody know if it makes a difference? bought the master cylinder from Napa in OR and I'm in WA (where my Bronco currently resides). I am hoping to get my disk brake conversion done this weekend so I can drive the Bronco back. I'm going to call Napa tomorrow and see if I can exchange it at a store here, or if I can buy the right one and return the other when I get back. But if both of those fail would the 4wd master cylinder work every bit as well as the 2wd? Or could I maybe drive it down on the drum/drum master cylinder and still have acceptable brakes until I can get the right one?
I would just put it back together stock and drive it home but the front brakes don't seem to be working at all right now. Also does anybody have any idea how much it will cost to have a machine shop turn down big bearing spindles?
It's not easy being this dumb.

Lots of guys have good luck with the stock master cylinder. Give it a shot. You just need to take out the residual pressure valve in the MC.
