MG008 is the one to go for, I dispensed with the ali deflector all together mounting the mud guard through the existing holes in the swing arm with about 50mm of mudguard protruding below the swing arm.
Use the ali deflector plate as a template for trimming the plastic and drilling the holes.
A block of 3 x 2 on top of the tyre is a good place to start for clearance.
I've had 30 stone of driver and ballast in the car without any fouling of tyre or boot liner.
