Finally after 400 odd spot welds drilled out, the floor and firewall is separated from the uni-frame.
Quite substantial as 4" deep and further reinforced with another hat section inside of that as well.
Good to see how well all the galvanized steel is coated through and through. Was even between each layer of steel also.
Will be leaving the floor stiffener in place as it is the rear mount for the seats and seat belts.
I did quite well on drilling out all the spot welds too with one or two one breaking right through the floor panel that I wanted left undrilled apart from the pilot hole. There was a few others when a bracket had to be removed from the top side as well so had to be drilled from both sides, but not bad going when you have to stop the drill bit each time only 1.2mm short of drilling through. Learnt a trick right near the end of tapping in a cold chisel into the joint and then you would here a crack just as the spot weld broke from the floor. Of coarse only discovered this with less than a dozen to go!
Not sure if I can keep where the cowl juts out or not. It was for the air intake for the heater and A/C and where the wiper motor and linkages sit. Not useful for either as they are needed under the cowl in the Willys and not the bonnet where this sits in the Grand.
Still undecided on how to best use the rear suspension mounts. At the width it sits, the rails with upper and lower control arm and coil mounts would nearly fit between the Willys chassis whole. So could leave them mounted to the rails and weld this to the inside of the Willys chassis.
I will keep this section as one piece until I know how to use it best. Want to use the mounts either way and they are made from HSLC ( High Strength Low Carbon ) steel and is 30-40% stronger than normal steel and has a higher corrosion resistance as well.
