If you go down to the last few posts in the 4.1 parts wanted thread you will see that I put the 3.8 up for sale and the reason I tell everyone to go there is that most everything that applied to the 4.1 also applies to the 3.8 except there is "no" scrapper and the only aluminum oil extension offered is for the RJC deep oil pan which is the longest one they make because it goes with their girdle and their deep oil pan setup.
You will get everything that is listed in the very first post but the scrapper and you will get the longer oil extension. Just substitute 3.8/20 bolt where it saids 4.1 or 14 bolt.
