I used DMTs which came as part of my firewall kit. All good.. I don't know if he started to include grease fittings, but you can get them elsewhere. (Schumacher has press in style in there kit.). I tapped mine for threaded fittings. The most important seal as far as stopping leaks is the butyl strip around the base. I had to redo mine cause I did not put the grease zerks in at first. Luckily I had butyl rope caulk left over from my windshield install.
