Merv, Race Brakes recommend an AP four piston conversion for the front (commonly done for the Brute Utes) and the other suggestion from Kenmer has been Wilwood with an adapter plate which they can supply. I doubt I'll be replacing the fronts this side of xmas, just doing the back brakes properly for now.
I've painted one half of the cradle in POR-15 and it looks great. I might start another thread as I start to reassemble everything - if only to share the eye candy as I realise I'm not breaking any new ground here.
