FRONT FENDER/MUDGUARD EXTENSION

Does anyone know where I can get a mudflap / fender-extender for the rear end of my front mudguard (to stop mud, dirt, stones from being thrown up into my radiator) ?
Thanks for any help you can give.

Hi Phil,

Did a quick google search and found these. The price is right. and you could install some chrome studs to dress them up, if you wanted.

I was just thinking...this rear flap would be just the ticket when pulling a trailer.

Or even this maybe,

Many thanks guys. I've made up a rubber flap for the front mudguard but I wanted something to fit inside the mudguard (between guard and tyre) and there's not enough safe room for the rubber thickness and bolts / washers.
The fenda extendas are ideal but I haven't found one the right width and contour.
