Got a few hours spare to at least do some clean up in the back.
Been spending a lot of time before that working out exactly what needed to be done to fit the suspension and drivetrain into the Willys frame.
I don't want this sitting jacked up in the air as want good road handling, but it wont be sitting on the ground either as not the theme I am going for. It must remain perfectly practical for interstate drives etc.
My limiting factor was the underside of the front guards. I can only drop the body over the suspension until the upper front wishbone, at full compression, does not hit the underside of the front guards. To get the whole Grands sub frame to sit under the frame to get that height, I have to step up the height of the front of the chassis by 2" while leaving the chassis under cab unchanged.
Who says I don't ever get the floor dirty! Was a good bucket full to clean this up.
So now have the floor and its cross members out and the fuel tank.
In the rear the frame will be kicked up 4" and will be running level with the top of the old cross members that supported the floor. I intend to drop the floor cross members in between the frame rails to keep it low in the stock position and so there is no big step up when you open the tailgate.
The 4" rise will mean I can install the rear suspension at the same relative height as it was installed stock in the Grand compared to the front. This keeps the roll centres front and rear at the same height as when installed in the Grand. All suspension points, including upper coil mounts, will be made to be at the same height as well so will be running stock control arm and panhard angles.
Any further ride height adjustments will be fine turned with different coils front and rear.
