I got Goodrich stainless steel braided brake lines + 2" from first four offroad in the uk. You could probably get them from loads of other places. As for abs extensions, I found I didn't need them but if you do - expedition exchange sell them. Google them they have some cool stuff but$$$.
I have the 40mm lift billies in my SLS d2 and they are great. A little firm unloaded around town on bumpy roads but load her up for a trip and they are great.
