Little body help??

[mark69k20]

Finally got her! Now all I have to do is fix her
I am looking at the cab as a good starting point.

For all you pros out there where should I even begin with this floor rot? I am going to order up all the patch panels, prob from LMC(taking sugestions). Then where do I start?
I figured as I cut and paste these new panels in i would want the cab supported w/ doors and fenders on to keep the correct body lines.

Any suggestions as to order of replacement of the cab supports, pillars, corners, rockers etc? This cab is a mess, any good tips for a capable yet inexperienced individual?

Thanks!
