i have done this during the previous weekend, not difficult at all. i used a hacksaw blade to score what was left of the mount and broke it out with a screw driver. i replaced it with an OEM part as i wanted the idle to be as smooth as possible. putting the new part in required a bit of improvising, i used a C-clamp & a piece if wood with a hole drilled in it so that the pressure would be distrubuted along the perimeter of the bushing. the hardest part was getting it started without the bushing becoming askew. if you do use OEM note the position of the arrows on the current bushing, mine were veritical and start at the flared end.
