Ok, so I just received a set of T-Rex frame sliders I ordered. So now I need to install them. The instructions refer to the bolts as M10x50mm, 45 and 90mm. So is "M10" the size allen wrench I need to get to mount these? And it mentions tightening the bolts to 30ft/lb as per the engine manufacturers spec. Soooo, do I need like a torque wrench or somethin? I can deal with electrical things, but I'm not really "mechanically" talented
