Cab Dilemma

[Crazy Rusty]

I think I already know the answer but wanted to get some opinions...

I have a 65 C10 that I'm working on that's pretty rusted out. Rockers, cab corners, most of the floor pan forward of the seat area up to the crease of the firewall on both sides, some of the high hump, a few cab supports, and the kick panels of course. Nothing I haven't fixed before but obviously a lot of time/money going to be invested in welding that all back to a proper state.

I just traded an old race engine I had for a parts truck that's in MUCH better condition than mine. I live in NW Washington and it came from SE Washington, more like desert country. Rockers are solid, floors are solid, a few minor floor pin holes... pretty great... But it has no vin and it was an auto, so no hump hole at all and I'd want to keep my four speed.

So... do I keep my rusty cab and fix it up or work on getting this cab licensed and put a high hump in it (which seems like it might be hard considering mine is fairly rusty to use as a template). Thoughts?
