Needing to order patch panels for 70 C10

[65 GMC]

I usually hang out in the 60-66 area. But anyway my younger brother has Grandpa's 70 C10. He is wanting me to repair the cab rust in it. From looking at the truck this weekend, it looks like the floor supports are solid. From what I can see it will need inner and outer rockers along with cab corners. I usually order my 60-66 stuff from Top Banana. I was looking at their 10 piece 67-72 cab repair set, it looks to have most all of what I need. Is their 67-72 stuff any good or should I order from someone else. Thanks for the help guys.
