Tony - Maybe I'm "out in left field without a glove" on this - but maybe you'd be better off trying to chill the pins down if possible.

Heat sounds like it would be great at fracturing any type of rust bridge between the pin / bushing interface - but it will only be working in your favor if you are heating the outside bushing itself (expanding it in effect) - not the pin.

I'd try chilling down the pin itself locally with dry ice or perhaps an aerosol product (Loctite makes one I believe). It looks like you may be able to get access directly to the pin head and the tapered tip enough to make a difference (provided of course the bushing does not extend the full length of the internal cavity)........ If you were to chill down the pins you would in effect be shrinking the pin diameter thus increasing the clearance between the pin / bushing. Combine this with one of the above pneumatic methods of agitating the connection and you should be getting some movement.

I'd hate to see you have to hacksaw / reweld the stabilizers !!
