OK fellas, listen to this. I'm very excited about this project. I will try to get some before and after pictures of this deal to post for ya'll. Anyways, the bed floor of my '72 is very holy, and I don't mean in the biblical sense, and rusty to boot. I'm moving to Buffalo, NY in January, where they salt the roads every so often, when they get a little snow. So, in order for my whole truck to not fall apart within the first 3 months of living there, I'm am diving into the biggest project thusfar on my Blazer: replacing the ENTIRE bedfloor with 14 ga. steel diamond plate and some 12 ga. flat for the corners. While I'm in there I'll also remove most of the stiffening "cross-channels" with a 3"x3"X.125" box tubing to take the place of my bodylift pucks that will double as airtanks. Finally, in the rear, where the tailpan is, the diamond tread will wrap down to the frame and I'll replace the channel that is currently back there with a 5"x5"x.25" box tubing that will also double as an airtank. After I get all of this taken care of I'm going to undercoat it with POR-15 or Zerorust and spray the interior with a tan Perma-tech liner!! I've even got enough stuff leftover to replace my rocker panels and fab up a custom gas tank. I AM STOKED!!!! Just for those who are interested, Buddy I've got my dream truck and it's a 72 K-5 that is getting there!!
