I put a mid-70's truck box forward of the axle, made my own bracketry to mount to the frame. I used a tilt column from a mid-70's Monte but you can modify the original column to work (I think). I made a steering column shaft from all of the pieces from the donors and made a pitman arm to connect to the original steering linkage. Later I found that a mid-70's 4WD steering box works the best, it already has the proper pitman arm. I may still have some pictures (as crude as they may be) on my computer somewhere if you need a reference to look at.
I've never done a 1/2 ton but it shouldn't be that much different, just a few inches here, and a few inches there,etc.

P.S. Everything I did was home made so it didn't cost me a dime. Even the P/S hoses got modified no problem.
