Hi I bought genuine mud flaps on eBay, from 2 sellers, 1 set of front (new ones) and from another seller the back ones, this set was from a scrap yard, (near my home) and they allowed me to take them off the dearly departed Jazz!.
The only tools needed was a star type driver to undo the screws,
I'm a OAP and I cheated buy having a couple of old pillows for my knees (front ones) and my head for the back ones.
