Manage a little bit of time back on the project. Wont have as much time this year as have to fit it in with house renovations.
I dragged out the Grand Cherokee firewall and floor from the garage. This will be the basis of the body build and the Willys cowl and sides etc will be welded to this.
I have cut the part off that supported the wiper motor at the top of the firewall. Can't mount the wipers there as the windscreen is a good 10" or so back from the firewall on the Willys.
Next thing to decide is how much wider I will make the Willys cab. I want the tyres fully covered by the stock guards as is required by the law here. Don't want to just widen the guards as don't like the look of it and more cab room is much needed too.
The extra width is determined by the difference in axle width, (57" Willys, 66" Grand Cherokee), and any change in wheel offset and tyre size. So have to choose that already.
I also threw on the Grands original dash to see if the width I choose effects the use of that later on if possible. Most of the dash depth will actually be under the cowl and only from the top corner vents forward will be visible, (will cover the speaker grilles). This will improve the looks of it even though I am going for a modern inside and underneath, and old in the body only look.
