Readying for rust repair (rockers and floors)

[A-man930]

Well I've given it all I had and held off the rust cancer for a long time, but I think the day is near when I'm gonna have to get serious and do some major work before its too late.

 

I've all but decided on Spadano Enterprises ROCKer panel sliders to take care of the pinholes developing on the outer panel (http://spadanoenterprises.com/-mj--comanche.html) but I'm not sure about the inner rockers' condition.  Is there any way (short of drilling a hole and poking a flashlight in there) to get a heads up on how they are? 

 

I took pictures of the floor issues.

 

Water likes to sit here and I was prompted to peel up the bedliner coating and found this:

 

The driver's side was patched with fiberglass years ago and is finally failing; I'm not so certain a replacement floor pan would cover this far up the footwell...  

 

 

 

The passenger's side isn't as bad, but the firewall looks different to me... has this been fixed before?

I literally just did this to mine. That looks factory to me. I went back with 18 gauge sheet and made my own patches.good luck! A set of wire brushes for a grinder would be a wise investment

I spent a bunch of time pondering under it last night and all but decided to pull everything out of the way, strip the entire floor (inside and out) down to bare metal, fix the actual holes, weld in a Claytons crossmember, and seal it all up fresh. I'll deal with the rockers later.

You get a hold of a Flux wire welder and I'll help you out

You could cut the rockers out and slap in some 4x6 tube
