NewArt,
just to give you an idea what your going after, below are the tensioners and guides that I replaced in my 04S.
I replaced them all even though the tensioner from the IMS to Crank was the only one that broke. The others had metal pieces embeded in their running surface.
I'm glad you liked the 2X4 brace (the art of necessity the mother of invention). What do you think of the copper drain pipe thermostat removal tool!! works slick.
