I've had a few of the Offroad Armoury's skidplates! This was the first one I had -

The MkI version... (above) plenty of holes to led the mud out...

The MkII version, these were brought out to match the front axle drop brackets I was selling at the time (I later fell out with the supplier and now buy my drop brackets from the ORA), with drop brackets fitted, the front skid plate needs a bit of a bulge to allow the front of the diff to drop slightly. (We fit the drop brackets to alleviate the strain on the front driveshafts... dropping the front of the axle flattens the angles that the driveshafts - especially the CV joints - run at).
The ORA normally supply these plates bare steel or powder-coated, I prefer mine galvanized (personal choice)... especially as I can get it done cheap! ;)
The two above were for my truck, and one for my mate Richie (green "Eco" Diesel commercial Vitara).
Fitted, you can see the brace that runs between the two wishbone mounts, and then the skid plate bolts to that... the rear of the skid bolts into two existing holes in the chassis crossmember behind the engine... where the back of the front axle sits.
Close-up, note the ORA Sargeant Stripes logo on the front left.

Aha, here's the middle skid, this covers the gearbox and transfer box, this has just come back from being galvanized (dipped in molten zinc) as it was kindly supplied bare to me from the ORA, the first one of the production line ;) Note again the sargeant stripe logos, and loads of holes to let the mud out!

From the side, you can see the neat rear mounting...

With the U-Bolt snugly fitted round the rear crossmember, the front of the skid is resting on a trolley jack, then it's just a matter of lifting it into place and slipping the washers and nuts on through the slotted access hole under the plate...

Again, the slot is just the right size to get a socket through and tighten in all up...

Viewing the new plate in place... nice and shiny, for now... ;)

...so it matches the front one... or will do when it's been scratched over rocks and dragged through the mud ;)
Many thanks to the ORA ;)
