Needless to say, I gained some pretty good brownie points with my father-in-law.
Part (Meyle brand): $45.08
Current out of stock, but this is my source (very well-respected with the VW crowd):

You can also get a few of the steel rivets, which I bought, but then I just stuck with aluminum rivets since I had a regular hand rivet gun from Harbor Freight ($7) that couldn't grab the super-long mandrels.
So for less than $60 and about 90 minutes' labor (first-timer), I knocked it out. Not too bad at all!
