I moved to Europe beginning of this year and decided to take my JK with me.
Since the US has the high and narrow plates and Europe uses wide and low plates, I needed to come up with an idea to fit a wide plate on the back (doesn't go in the stock plateholder) and besides, I want to keep my American plate on there too since that looks cool over here.
In Europe, they fit the plate under the spare wheel half on/half hanging under the rear-bumper. Which looks rediculous in my opinion.
I wanted to put it on the spare wheel, but removable without any tools. So here's what I did.
On the lathe I turned 2 bushings with the 75 degree angle of the wheel nuts so they would fall flush with the 2 remaining wheelstud holes in the spare wheel.
Then drilled a hole of 12mm in the bushings and turned 2 12mm pipes to slip-fit the hole in the bushings.
With the pipe inside the bushings I drilled a hole through all to fit a pin that holds both together (and is easily removable in case of a flat tire)
I drilled a hole in the sparewheel holder for a pressfit on 12mm. Pressed the pipes in until the bushings sat flush with the spare wheel, welded everything together and made a bracket on the 2 bushings that holds the plateholder and a little light for the license plate.
Wired the light from the right-taillight and all was done.
I thought, maybe someone likes this idea for a Euro-plate in the US or something so I thought I'd share.
