I got them custom-made my a steel fabricator in Kettering called Billson's Steel Services. If you ring them ask for Glynn and mention my name if you would. They're properly "Old School" and although they mainly do structural stuff they seem to enjoy a challenge. They started out making boilers for steam engines, so they've been about a while!
They cost me a bit over £400, but I know steel prices have risen since I ordered them (it was ages between ordering them and actually having them fitted as either I was away with work or the car was off the road...) but the quality of the work is great and its doubtless cheaper than trying to rplace or repair knackered panels or plastic.
They're still only primer so I'll need to paint them up properly at some point.
Btw, if you're still considering going to Japshow on Sunday then I will be there - whether or not there's a space on the Yaris Club UK stand remains to be seen though
Cheers again,
Alan
Edit: nice bow wave!
