Thanks for the replies.
I will try to be careful when pulling off the wipers.
I guess I should have figured the gasket was for the cowl panel cover.
The parts catalog I use is not interactive like the one from the Auto Atlanta site, so I couldn't click and view.
When I click the part number, it's obvious that's what I need.
I will bookmark the interactive catalog for future needs.
Problem solved thanks to the fine folks at 986forum.com
