my front hangers are correct and all the measurements from cal tracs that they have told me to measure all measure up. 117 is the wheel base on a stock charger as the internet says mine with the caltracs is 117.5 the axel is directly in the center my wheel well is 33" the axel is 16.5. the only thing im worried about is pinion angle and will the u bolts be under any added stress that they will snap. Thanks
