[s-cars] Which stereo tool?

[Konstantin Bogach]

Hi.
I have a tool using which I successfully removed Delta radio on 200tq but I can
not remove Bose stereo from UrS4.
I bought the tool in Pepboys as "Ford stereo removal tool".  It is U-shaped steel
rod with groves at the ends which makes the end ball-like.
When I use it on Bose stereo it goes in and out and does not bind.

Are there different tools for that?

Thanks.

Konstantin.
