Found a few things waiting for me after work. Still waiting on some other bits and pieces, most importantly the bracket for the LED bar...
Tyres are Buckshot Mudder XMT's 285/70/17 - Going to put them on the stock rims. Got them for $175 each, so compared to paying $500 for a BFG here in regional WA it's worth it even if they do wear out in two years time.
