Hey I know you can buy color coded plugs from america, but I am not paying £25.00 + shipping + tax to get them delivered when I think I may be able to make my own. I have seen lots of people with small plates and I cannot see any existing holes which is strange as mine are standard holes done by Audi and have not changed, they are exactly 18 inches hole to hole. A standard plate is 20" so how are people getting the 5 and 6 digit plates without seeing the holes in the boot? How do people get small plates without seeing the manufacture holes? I was thinking of painting a flat screw cap cover in my dealer color and just use pvc glue to cover it. I want a 6 digit plate size, but if I do this then you will see the holes in the boot as a 6 digit plate is 14 inches I think? What have you all done if you have short plates ?
