I am surprised that your '79 had unbushed tensioner arms.

Looking through Anderson and Dempsey, I find that the wide arms (which required narrowed tensioner bits) came in in 1980. These, of course, had bushings.

But my understanding has been that the unbushed arms were found only on very early cars. My '77 Euro, which rolled out of the factory in the summer of '76, had the narrow arms, but they had bushings. When those of us who had a 911 in the late 1980s were busy installing Carrera tensioners, the decision point was whether to replace the older, narrower arms with the newer version (a question, as always, of $), or to use the aluminum spacers which came with the tensioner kits which filled the gap left by the narrow tensioner part.

I didn't find reference to unbushed/bushed in Frere, Anderson, Aichille, or Dempsey. I didn't get out Ludvigesn.

Someone no doubt remembers when the narrow arms got bushings.

Or maybe my memory is playing me false.

Very interesting thread.
