Need can followers

John I just have to be a bit of a smart-ass here but there are a few different varieties of cam followers. Do you require crowned or flat, regular or heavy stud or no stud, maybe an eccentric stud? Ya got the part number of an old one? Not all cam followers are the same and just stating the od is not all of the information required. I do have some but will not go digging till I get a narrower request. Can you search out a McGill catalogue and give us a part number? lg no neat sig line
