I need to update the resto doc with the information about the passenger-side speaker placement. Looks like we've got both out there.
Hopefully Jim's source can get us a bunch of the antenna clips. I posted up a picture in the in-service section of a bunch of '87 cars, and there's a nice shot of the correct bracket (Mike C. has it on his restored '88). Interesting, also, is that the clips are angled over pretty far.
