Made some progress over the weekend. I found a cab on Craigslist, it is pretty solid too. Way better than any we have including my 70CST. The supports and floor pan are solid as a rock. The only real rusty areas I have found (so far) out rocker (they started pulling the pass.), lower cab corner and front left top of the firewall.
The previous owner decided to start shaving the drip rail, so I will have to finish that and they cut the cab in 2 spot to "body drop" it. I don't like the fact they just cut the whole rail off instead of a little at a time, hope it works out right. All in all not too bad for $100 IMO.
It will take way less time to fix than the original.
We cleaned a bunch of junk out of my shop to make room for it. Now I just need to find a bottle for my tig welder. BTW, anyone know if I can use straight argon to mig weld with? or just the 25/75 mix? or vise versa? can a tig use a mix? I have a Midstate Tri-arc and it will mig, tig and stick weld. Here are the pics of the cab:
