I ordered a replacement stabilizer set.
It should be here tomorow.

Now, any advice on removing the broken stabilzer?
It was glued with epoxy. I asked in a store and they said there is no disolver for epoxy (only for CA).

I will try to split it with knife but somehow don't feel it will work well... I am afraid not to brake the body.

Or I can brake out the stabilizer and pile the epoxy...
