I'm resurrecting an old Ivanko bar from the mid-80's. Using it on an olympic-width bench, so I need to have some clips since the weights are near the bar-ends. The collar size is slightly over 1", about 8/100's. Typical spring clamps don't fit, but I've got one (from off a rack of spring clips, but only one) that does. The guy who sold it to me remembers that they used to have slightly over-size clips for the Ivanko bars back then. Anyone know of a source for something like this?
