Update: I threw in the towel and got the hood-liner (aka silencer) from the local dealership ($93), with the 14 rivets. Just replaced last night, and will post pictures soon (easy and no hood removal necessary).

If you are careful when removing the old rivets, you really don't need the new rivets. At almost $4.50 apiece, there is motivation to be careful. Since I knew I sucked at DIY, I had to buy the new rivets in case...

The old liner was pretty much eaten up on the inside. Rodents nested there for sure...

But I do have the old liner, and it won't be too difficult to use it to draw a template for Gonzalo to use, if anyone is interested in getting his custom liner.

I also have 14 re-usable rivets, if anyone is missing any (PM me).

EDIT: pictures added

OLD

NEW with one more rivet to go...
