Measuring for the Z... 4.5" up and 1" forward
Cut away
Tacked back up
Material for the new frame rails... Went with 4"x3" 1/4" wall tube
Drew up an actual full size blueprint so I could make sure everything was right
New rails started
Weld porn... All joints were prepped and beveled to insure proper penetration
