I think the mod is not compatible with version 0.37. Even though I cleared the cache, it did not fix it.
v0.37 Update! -Fixed Texture Problem -Added Glowing Brakes Nothing more (currently no time for that) Link on the first post
the 1.7.5 broke the mod for me i'll try to fix it fixed it, i think new problem: the smg shifter falls loose when hitting a bump
