Righty then...............
I ordered one of these today...........

£41 from the main stealer. Arriving on Wednesday. Not sure wheather to go with 2 weld bits of angle onto the engine bed or to design and make a sturdy aluminium bolted bracket to attach to the bed??
I'll drill and tap the holes M10 x 1.75 and fit the mount first, then go about the design of the bracket in the next few days after that. The most important thing about putting the holes in is to make sure i've got anough room to get the right angled drill attachment in and then keep it square to the face to be drilled.
I'll make up a little drill jig too me thinks.
