Well with cruisn, Mark, as busy as ever, I thought I'd get off my hands and have a crack at a number plate spacer kit.
Went down to Bunnings to have a look see and came back with a 20mm X 3mm aluminium flat bar for a total cost of $5. I think that's the least I've ever spent at Bunnings. I am on a pretty strict budget to get the car finished so was happy with my self control on this occassion.

Took me an hour to complete and I'm pretty happy with the result.
A before an after pic to show the difference.
