New Project 57 Chevy panel on 78 chevy frame

[T-P Auto]

Hello;

Well got the big window cab to the shop this week.
Looks like I need a sand blaster to get the cab clean to find all the rusty places.
Found the most likely places floor board, lower hing panels,
I look to have some good cab supports, good firewall.
Have two door hings that the bolts will not come off, both are the innter bolts.
Looks like I need rocker pnl n steps,door hing plate,hing pillar inner.
Have several pic to load on this site.All showing the places that need the work.
