Albertr -
As you see, I have the Alpine. I had one zert fitting that I don't think would take grease with even a million pounds pressure (Imperial measurement system there). One quick visit to the auto parts store yielded a package of new zerts plus a half dozen spare zerts! Got the metric crescent wrench out, and in less than a minute, the new zert was in place and taking grease! It is just the standard zert fitting, but if you have problems finding them, PM me your address and I'll mail (post) you a couple. Can't you see the Canada Post customs guy looking at the green tag thinking "zerts?!?!".
