It's hard to get at em, and laying on the floor under the dash is hard on the back. But an easy fix once you get the linkage out. I assembled the linkage outside of the car, then snaked it up under the dash and connected it to the motor and pivot arms. You may want to take the time to replace the seals/gaskets on the pivot arms while your at it as well.
Several threads I searched out here helped me a lot. Tips like soaking them in hot water to soften them up and using plenty on lube were very beneficial.
