Removed the old parts and installed the new parts. Very easy job to complete.
The hardest part was putting the spring in place. To compress the spring , I used a medium sized flat screw driver and placed it in the end of the spring so it screw driver went part way in the spring and the wider part was able to push on the spring and with my other hand, hold down the rest of the spring and components and pop the spring in place.
