I broke mine just leaning a gas nozzle against it. They are made of crap pot metal....not a billet or even machined steel.....it's "white metal"
The new one from Merlin cost maybe 40 bucks....
**THE RUB
They were mounted to the cladding BEFORE it was hung on the truck. There is one screw that goes in from the back. I did manage to get it on without removing the cladding, but it was not real easy....patience (and small hands) will win out.
I wanted to look around for a Billet replacement, but got lazy and just ordered from Isuzu....figured attachment points would be different, but I don't know that as fact
Good luck mate
