I was trying to install my new valve and i can't get the hammer to some out. I have screwed the sear lug into the hammer but the hammer can't get past the treads in the back. Am i just stupid and bought a vavle for an autococker that can't have a new vavle or do i have have the back drilled by an airsmith. Any help would be great guys.
Oh by the way it is a 99 sto
