I take mine to a shop in Green Bay if the work is beyond what I can do, but that is probably quite a hike for you. This particular shop will install your parts after they inspect them. Usually you will need to sign a waiver as they cannot guarantee functionality or quality, however this is very rare. Most shops do not want to deal with the possible liability or problems that may arise from parts that they did not supply.
