@ctc, thank you, some how I missed that note entirely. It has been 5yrs since I bought it but I went back and reread it trying to figure it out, I must have skimmed it because it is there as plain as day.
@ Tony, Yes I was assuming I needed to bolt an additional pulley to the end of the damper but I am learning that I really need a 2 groove damper instead. The extra pulley on the end must be to drive the power steering and I don't need that.
So I need to find the right damper. That BHJ product is painfully expensive though. Any lower cost alternatives? Without replacing my 30yr old part?
Thank you both for the assistance.
