4x4 frame repair *PICS*

[Campbel45]

Hows it going guys. I'm about to POR-15 my frame and when I took the bed off I found part of the rear frame deteriorated and would like to weld in some C-channels. Confident in welding but would like to see some pictures on how far back the frame is supposed to go from where mine is currently is, and what it looks like stock as I have a homemade rear bumper(not my doing) that is pretty think that I think is being used as part of the structure right now. It is a 1971 short bed k10. Also there are some holes around the shock mounts. Doesnt seem like it will be have that hard of a repair as long as I make templates and measure correctly but does anyone have any advice they'd like to give or any similar experiences?

















Also this little guy (needle scaler) is awesome for busting up scale, rust, and what have you. I highly recommend having one in your arsenal.
