This is a listing of parts I have replaced, or researched thinking I needed to. Remember, this car was built in 1979 and sat unused from 1990-2003, so a lot of things needed fixing for my restoration project. I've done my best to indicate those parts that are specific to the 931, installed options and/or certain year models. Do not take what I have listed as "gospel", as I may have made a mistake, part numbers are frequently changed
If the part number is highlighted, click it for a photo. I use a variety of parts sources to obtain repair parts. Here is a listing of my favorite sources. See the note at the bottom regarding pricing.
