lukc is on the money with the Salomon suggestion.
I've bent Tyrolia brakes to fit my 136mm-wide Praxis. I broke the first pair of brakes and ended up having to enlist an engineer friend who has his own metal shop to help bend the second. Tyrolia brakes have three disadvantages: (a) the widest brake available is 115mm; (b) the metal is very resistant to bending, and requires either heat or serious tools to bend properly; and (c) because the screws that hold the bindings on the skis pass through the brake assembly, bending the brakes after they are mounted stresses the mount.
That said, I don't know what Whiteroom is asking, but Level Nine has your choice of 2006 FF+17s
(6-17 DIN) or FF+20s
(10-20 DIN) for $139, +115mm brakes for $30, +$10 shipping = $179.
