i dont have any plans, but if you go into an ARB store they often have the complete set hanging up on display (well the last few i have been in did). Maybe you can do a little sneaky measure up with a few photos.
Get underneath with a pencil!
There is a thread kicking about here somewhere with details of ironman bash plates coming out soon, don't know if you'd beat their prices getting made locally, seem reasonable
I've got a set of ARB plates and have only fitted the transfer case one so far If you're near my place (Western Sydney) feel free to measure them before you help me fit them
i got mine from mine corp it starts at the bull bar and gos to the back of the auto and is made from 4mm checkplate steel and its bloody heavy but has saved the truck many a time
it was about $800 i think 4yr ago
