A way to fix this with a ghetto solution?

Others will hate this but it works, especially as its only a spacer.

Wrap the broken bits tightly with electrical tape, the force of the dropouts and axle will keep it all together.

I did this on one bike and it lasted for over a year until I got round to sorting it.

You did say ghetto fix right?

** I take no responsibility if this method fails and you kill yourself **

Wow, have you any idea how expensive electrical tape is these days?
