Rocker panel and cab corners. Advice??

[odin]

My 79 GMC is gonna need rockers and cab corners.
It seem like just yesterday...like 15 years or so ago now, I swapped out the badly rotted 79 cab for an 87. Which was mint.
Not any more. The 87 cab is starting to show its age now. The cab corners and rockers are starting to rot through.
Any advice on which ones to use? Goodmark etc. Are GMs still available?
Any tips and tricks would be appriciated.

Parts

I would try LMC, or Goodmark first, if not there try http://www.rustrepair.com/ I've used all of them before. Each are good sources for replacement sheet metal parts.

wouldn't recommend rustrepair.com/mills supply to anyone. no shipping charges quoted and then a huge cost after. stuff i got from them so twisted out of alignment and dented with no recourse.
highly reccomend lmc, got my order and the rear quarters were dented and banged up bad from shipping and not enough support in the packing. called them and they sent out 2 new ones asap, N/C.
