Al, if they are standard edge-type posts then just get your hands on an M8 x 30 (or so)...
remove the trem posts and screw in the M8 bolts you got... they can take more abuse and are cheaper !
using a piece of scrap timber to protect the
guitar body use a claw hammer or similar bar type nail removing tool, slowly tease... mm by mm the post from its home.
always tease and dont move the bush at anything other than a perpendicular angle to the body..
TBH a bearing/stud puller or similar would work really well on removing the bushes but im yet to try one out cos the claw hammer always works
