Sorry for the small pics... im using Tapatalk for the first time...
The frame is solid... it has a nice ring when I tapped it with the ballpeen hammer.
Im addicted to these trucks and honestly parts are very avaliable for them but they cost a bit more than your average chevy truck pieces out there.
There are some great vendors that offer up deals every once in a while and your right, the surplus stream is steady and lots of parts swap over to the civilian side.
Ill try a few different pics... maybe they will be bigger.
