Hi Fedcourtdawg. In the UK and just about anywhere else other than the States what you call fenders are called wings. So you’re looking for wing mirrors. Plenty for sale on eBay usually. On the P4, P5 and P6 they usually just bolt through a hole drilled in the wing; they don’t have any relationship with other trim items. And they’re usually useless for any practical purpose, in my experience. Door mirrors work, wing mirrors are just for show.
