All Front subframes the same?
 

I realize that there are numerous suspension differneces between the various FC's, differnet lug patterns, brake sizes, auto adjusting suspension etc etc. But if I were to get the front subframe from a FC, are they all the same between the various years? What about the steering column, do they differ by year as well? I'm considering swapping the whole FC subframe and suspension into my FB, and I'm just trying to figure out what I should be looking for in the junkyard. Thanks guys
