Converting a 2wd cab to 4x4

[ChaseDale3and8]

I asked this over in the 73-87 section with no responses, so I'm going to try here. I have a 1986 2wd cab that I bought to go on my 86 K10 chassis. I have finally located a bolt in high hump center section. Is this the only part that I need? Just mark and cut out the section of floor that needs to go and then bolt the new center in? Is that all there is to it or am I missing something? The swaps that I have done in the past have all been 4x4 to 4x4 so I'm not familiar with putting a 2wd cab on a 4x4 chassis. ...Joe
