Modifying the piston out to fit your worn out pin is a bad idea, it will create a large internal cross leak and lower the effectiveness of the servo kit. If your original servo pin is mushroomed under the E clip, carefully grind your existing one back to size – otherwise it will not go through the new piston. NOTE: It is recommended that you replace your servo pin, most of them mushroom over time.

We will sell the other components of this servo separately, just ask.

You will have to disassemble your original servo and reuse some GM components.
