so I finally got traction on the front end today
started by tacking each of the plates into place then stood the chassis up on its side to get good welds
then we flipped the chassis upside down and lined up the c notches which were weld in.
then we mounted the subframe so he could weld down onto the underside of the chassis
then we righted the chassis and welded the top of the subframe in
unfortunately we had to stop there as I had to goto a day surgery but he's left his gear here and assures me he will be back Friday to finish the job off
