I've been following your post. Have you replaced your tensioners as you described in your post? Reason I ask is coz I will need to replace the tensioners on my 99 Boxster as well and have asked for guidance but have not received any post replies. I asked Pelican but no definite answers on HOW to do it. Do you have the tools to do it and where did you buy them from? Maybe I can buy them from you after you're done with yours.
