Turning a stub nose cab into a pickup?

[71stub]

So I found a pretty solid cab from what I call a stub nose truck. It's not a regular 2.5 ton truck. The hood and fenders are shorter on it. The fenders have a step built into them. It's not a cab over. My question is has anybody converted one of these into being used on a pickup chassis? I know the front corner of the door is clipped off and would have to be fabricated and the toe boards would also need to be replaced with pickup pieces. I'm not sure on the firewall. The cab supports look the same. Any help out there? Anybody else looked into it? Thanks in advance.
