'69 Fleetside bedside repair and wood floor replacement

[Oxmarqt]

So I searched here and on the Internet in general and realized that my Googlefoo was weak. Basically found squat so I thought I would begin to document this process so the next guy has something.

It all started when I noticed the Driver front corner of the bed starting to sag. Upon investigation I discovered that the flange on the bedside that sits on the wood had rusted away. Unfortunately I also discovered that the inner bedside at the wheel tubs was rotted on both sides as well as portions of the flanges at 2 other corners and part of the rear cross sill. Ugh...

The PO of my truck had covered the floor with plywood and then coated the floor and bedsides with bed liner. Oh well, I am taking the opportunity to fix the rusted areas with patch panels, replacing the floor with new wood, new cross sills, new rear harness(old one was cut and patched many times, get rid of the liner and Por-15 anything that the bed makes inaccessible. When I replace the rear trailing arms I will get a little more detailed with the Por-15 but that is down the road.

Purchased the bed wood kit, flange panels and cross sills from Mar-k, the wheel tubs and outer wheel house patch panels from GMC Paul and the inner wheel house patch panels from LMC.

Hopefully all goes well!
