Okay, I have the T50H (tamper proof) drive to remove the pulley, but I can't seem to find anyone selling just the pulley itself. Many places have the entire tensioner assembly available, but not the individual pulley.

There seems to be a good bit of confusion (on the parts sites) between the tensioner pulley and the idler pulley, with both descriptions being used interchangeably and substituted for each other. I understand they may be the same on later SC equipped models, but on my 2004, these two pulleys are definitely different.

So does anyone know of a good source for a stock, non-ribbed, early NA tensioner pulley, or perhaps have a specific part number handy that might help me search further to locate one?

Thanks very much.
