Hardrace Adjustable arms - no brake bias valve bracket?

Hi all,

First post, I did search I promise.

I got a great deal on a set of adjustable Hardrace arms and now they have arrived realised they don't have a bracket for the Brake bias valve?

My car is a Aussie spec SLX so drum rear but does have GTi-R brakes up front. Assuming I am going to need to weld the bracket on for my application and that disc rear Micras don't have the valve? (assuming the Hardrace items were designed for disc brake rear ended options?)

TIA for replies
