Not an expert here but referring to the overdrive pack, who would tow very heavy loads in overdrive? Wouldn't you avoid using overdrive while towing heavy most of the time?
Just got the stage 3 build it kit. All of the u/d clutches are the same thickness of the o/d clutches. Is that correct using the q100 plates? Stock one set is .49 the other is .59. In the kit all are .50
