I started the frame off by tearing down the truck.
The first step was to remove the Bed from the truck. Although I didn't see much online about the removal process. It seemed pretty straight forward: remove the carriage bolts and then use the engine hoist to get the bed off. Here's my photos from the removal process.
First thing to do was to lift the truck off the ground to get to the carriage bolts easily. Then the removal process began.
The boards were rotted from all the water and years of abuse. Removal took some prying and work.
Using the engine hoist I was able to take the bed off.
