What you need is a "P Clip" with a long-ish (inch?) M5 bolt. That bit is easy. The hard bit is replicating the washers that actually hold the "mudguard stay wire" onto the bolt. These are a thick (6-8mm) washer with a groove cut off-centre (imagine that the washer is a watch face, it would have a line cut through it vertically from 11pm to 7pm). You need two washers for each side of each mudguard, as they have two mudguard stay wires on each side iirc.
Most of this should be available from hardware stores, I have yet to find the grooved fat washers and so made some but not hugely successfully. My mudguards now sit in a cupboard awaiting my getting some DIY-energy...
Hope that helps - all from memory from a year or so ago so not sure. Also, apologies in advance for semi-hijack, does anyone know where I could get L shaped braces that would fit these? They bolt on to the mudguard, and then have a hole to go onto the bolt that attaches the brake calliper.
I don't believe that this was that expensive last time I looked:
