taking two cabs to make one good cab

[twillie2460]

Hi guys it has been a few months of cold weather and a few more months of refurbing the house for the wife but I am now ready to get back to the truck. I will post pics very soon but I am also wanting to ask about taking two cabs to make one. I want to cut both cabs in the rear post and seperate the cabs where the firewall meets the floor pan. The take the two halves and make one cab. My firewall\cowl area was gone and someone put a sunroof in the truck which I really did not like. I have been trying to find a thread on here or youtube video's on something like this but no luck so far. So any advice I can get would be helpful. I will post pics of the two trucks I have to work with tomorrow. Thanks
