Use it as a door stop.

Yes, you can get them rebuilt, but it isn't an obsolete item and places like Summit or Jegs will ship internationally.

There are a couple things that happen to them.

First and worst, the elastometric material will degrade allowing it to move in relationship to the keyway, making timing impossible to set. It can also fracture once it starts wobbling.

Secondly, the timing housing seal will wear a groove in the snout. There are inexpensive repair bushings that can be glued on, but again, why chance it with the other potential problem. I would suggest that you replace it with an SFI certified piece if you are going to turn high rpm's, if it's a grocery getter, then almost any vendor's piece will be fine
