I've put together a few bumpers in this fashion (not the JCR bumpers) and its not to terrible. Used to take me roughly 8hrs of welding and grinding to finish a bumper.
This is my Jeep. There are many like it, but this one is mine. My Jeep is my best friend. It is my life. I must master it as I master my life. My Jeep, without me, is useless. Without my Jeep, I am useless.
