i changed my plugs and used install university for
tips, but on the last plug #8 i had trouble with the swivel, so i used the plug socket and a 3/4 inch socket and rachet, no problem. you take the plug socket put it on the plug itself then take the 3/4 rachet and the rest is easy. plus it saves on the fingers. didnt know if was posted before could not find any other posts.
