AKG Bx15 suspension

Got an AKG BX15 and I need to repair the rubber suspension of the spring unit.  There are four rubber shocks that hang from a spring mounted frame to suspend the spring unit inside the main box and all four have stretched and snapped.  I tried doing some clever gluing but this is unreliable.  Does anybody have a solution?  I'm going to try mounting the whole unit with industrial rubber bands but I'd prefer the original solution if theres a way of moulding new rubber shocks or a possibility of replacement parts.

Thoughts?

Thanks.

Bumping this,

Just opened up my BX15 and it also had 3 out of 4 rubbers off.

Need a good solution for this.
