I am busy adding some belly (skid) plates to the front bash plate. There will be 3 plates in total (Bash plate plus 2 belly plates) which will overlap like fish scales from the front to rear. I wanted to make one continous plate for the gearbox, but installation weight and handling will become a problem.
I used 4mm plate for all. Another option was to use 3mm plate with additional crossbends or some stiffners welded in, but I settled for the straight bolt on 4mm plate.
This first pic is the bash plate lying on the second plate which covers from the bash plate to the suspension crossmember. Note that the holes for the rear mounts must still be drilled (as well as bigger 50mm vent holes if needed)
The rear plate covers from the crossmember to the gearbox support crossmember. The blue circle shows the clearance cut-outs for the lower suspension arms. The yellow circles are clearance cut-outs for the steering rack mouting bolt and the front diff. The plates hook onto the front crossmembers and then swing up to be bolted. This makes installation for a one-man-show (like myself) a bit easier.
Plates are 700mm wide but the rear plate also have 100mm wide 'wings' for additional protection. The third plate will be bolted at the rear OVER the gearbox crossmember with 4 x 12mm bolts in tubes (left over from my rock slider installation...) The front of the plate will be bolted through the suspension crossmember through existing holes.
