So I bought some Schrader valves to install in my XP turbos internal bypass shocks. Last time I did this was on a maverick, and I had to remove a plastic plug, then an Allen screw, then the rubber pellet, and then drill and tap. This one is different. It looks to be a piece of steel that was pressed in from the inside. It also looks like it's the right size for the tap. Do I just drill from the outside with the proper drill bit and then knock that steel insert out?
