way not just put in screw in studs and guide plates.guides plates are $17. and some change and rocker studs $50. and up.you need a good drill,3/8 drill bit and 7/16 tap.just cover all your galley holes up in the head and drill away.just hold the drill straight,then tap out the holes .if theres enough room you can do it with the heads on the motor in the car.then you can run what you want.
