I just took the bed off my truck over the weekend and need some advice with my frame.My frame is heavily rusted from cab back .I cut and welded frame sections on my 84 4x4 I used 3/8 thick diamond plate for the frame and 3/8 ssquarestock for the gas tank mount.I was alot younger then and didnt know much about welding.I would like to fix this one with the proper steel and apply chassis saver product inside and out.
