floor pan and kick panel replacement

[russellrox]

I am wondering how far up the full length floor pan goes up towards the firewall, my trucks pan is shot around where your left foot would sit and up towards the firewall, about 3-4 inches, about the same area where the front wheel throws dirt. Also the kick panel mostly on the left side, but also has similar rusty areas, the kick panel rust goes up about 3-4 inches. Will the new lmc kick panel and floor pan cover these areas completely or am I gonna have to fabricate some panels. Anyone have any pictures of replacement on your projects, also for doing floor pan and rockers would you recommend bracing the cab before cutting, if so, what kind of steel to brace it up so the cab doesn't shift and where would you attach it..
