Yes, no welding to the housing needed. For our FatBar, there would still be some welding needed for the Panhard mount, - but, we are going to change C10 FatBar kits to use the new C10 Panhard from the Trailing Arm kit, so those will be bolt on as well after Oct-1. (maybe sooner.)

As far as gears, a lot depends on the trans and tire diameter. For highway, we like to see about 2400 rpm at 70 to 75 mph. So the O.D. ratio comes into play. For most autocross, GoodGuys and USCA are mostly 'first gear' coarses, so as a rule, in first gear you want about 9.5" of tire roll per 1 RPM. So tir diameter can play big into the gear ratio here. 3.5 or 3.73 is usually pretty close.
