D.I.Y
1. I made up the number plate using a smaller font but also keeping it standard lettering
2. I masked off 1" around the letters and numbers then cut down to size
3. I sanded the edges of the number plate to make them smooth and used a grinding stone to round off the edges
4. I took off the lower grill
5. Upto yourself what u want to use to stick it on i used double sided tape but cleaned the honeycomb with thinners to remove any silcone or wax
6. Put the grill back on and away you go just give it a little time to settle then test it and make sure its not going to fall off
You could save yourself the hastle of making the reg up n just buy one precut just measure the size you require but some places want a fortune to make a smaller regHope this helps.
