Yes, absolutely. You need to measure the BCD, or Bolt Circle Diameter (ie the diameter of the circle of allen key bolts). There are various BCD standards, but you'll absolutely be able to find a replacement. Your freewheel might be a helicomatic, but it also might not. I wouldn't take that as quite such a given as people are suggesting.
