Cab removal

[1969k10stepside]

I just removed the cab on my 69 K10,it was a pain in the a**.I will never remove one that way again.I have another cab I am going to use so I was
not gentle with it.I tore up the floor a little and dented it a little getting
it on the trailer.I need a way to remove the cab off the other truck without
tearing it up.I will still have the glass in it when I remove it as well as
other stuff so it will not be all apart when it is moved.Any ideas?
Oh I will have pics later.
