Just looked these up on wilwood website:

If these will fit front and rear it should solve my issues as they are due to the dynalite's not having dust seals. Pity they don't do a 6 piston? If this will work for me I'm sure that there will be quite a few Aussie's over here interested to know about these, it's a huge saving not having to buy a full set of baer brakes just to keep the authorities happy, more $$ for engine!
