I honeslty use a stock WG and i just bolt up wherever i can, if its one bolt that allows me then that what's holding it in. If you have one already Cory just use the one you have take off the little arm and cut it 1/2 inch back that will allow you to have more boost. No need to buy another one, Here click in this link and it'll help you with picture's etc.. I stopped buying actuators, i have one that ive used for probably two years on 3 different turbo's always have a mounting issue so i just do what i can with what i have not that serious wont damage anything one bolt should atleast bolt up and as long as it's secure you should be fine.
