$110 is about right for the two bushings, the two wave washers, the two flat washers with the tangs on them, and the top plate/seal. I did mine last year.
1 each BOOT 6L5Z*7A107*AA (replaces the original 1L2Z-7277-AA boot) $51.58 list (7/2011 prices)
2 each SPACER E8TZ*7E018*A $3.17 each (7/2011 prices)
2 each WASHER 1L2Z*7Z120*AA $11.84 each (7/2011 prices)
2 each SEAT 1L2Z*7228*AA $10.70 each (7/2011 prices)
If you are on Garage Journal (hope the administrators don't mind my posting this link, if you do, just let me know, I'll edit it out)
I did a thread on replacing the the bushings and other parts. Similar to the thread here........
The Ranger Station Technical Library Thread on Replacing Mazda Shifter Bushings
But with more (and I think better) pics and more current prices on the parts.
