Quoted from LOTR_breath:Here is everything you need. Just $26.95 plus shipping. I would suggest buying the whole kit and if you're not comfortable doing the rebuild just yet, you'll have the parts later when you're ready.

The only thing that bugs me about the pinball life kits is they dont include the bushings. 95% of the time they're worn out too. I always replace the bushings when I do a rebuild. I wish Terry would include those in the kits.
