NS/NT front brakes bolt on but require 17” wheels IIRC and you have to swap the knuckles. Someone in the US did the swap and has the parts list. I think there is a thread also on the Pajero Australia forums.
Sliders you say? Perfect since I've bought everything else you make for the Gen 3 (if you don't count Marks t-case gears). Thanks for the Black Friday birthday present spending spree excuse. Looking forward to installing the skids and sibi bushings.
