Sorry for the delayed response time. Been traveling for business...
Red: yes, the part number I listed is for the DynaGear double roller setup that eliminates the tensioner. It's a nice piece.
1quikv6: yes, it sounds like you bought a stock replacement that will require the use of the tensioner. However, if you can get me a part number, I will look it up for you. Typically Pep Boys, and other aftermarket retailers are only going to sell the standard OEM type replacement, unless you special order an upgrade. I am assuming that's what happened in your case, but, another determining factor would be price. I've never seen a double roller set for less than $69, so maybe that'll help ya'...
Let me know if I can help with further info.
