I got this truck 10 years ago from my Grandfather when he passed away. I documented me doing a partial restoration on it then.
The truck has been sitting for a couple years, so I decided it was time to dig back in. Go big or go home.

I plan on documenting the build on here as well as my YouTube channel "Loudandproud"

This is the front crossmember design. Its .120" Plate, but pretty beefy for the application.

Right before I started this build, I made my own CNC Plasma cutter, so I plan on using it extensively for fabrication work.
