I have had excellent luck with all summit products because they are usually name brand stuff with a differnt label on them and a hell of a better price.
Were the rocker stud bosses originally machined for screw in studs?
The boss used for the press in stud has to be machined away, you can't just pull the press-in studs then tap the hole for a screw in stud. Additionally, when using guide plates under the stud the boss needs to be machined lower to also accomodate the thickness of the plate.
