Found this cheap UD pulley for my 97 OB on eBait, and bought it: Item # 8020647279 (for example)
I've read many posts about the downsides of running an underdrive, and since my driving is 90% freeway, I should have no charging issues, but what about quality? You get what you pay for...but what am I risking?
Install was really easy, in fact I had no issues gettting the old pulley off. I'm guessing that was due to the timing belt being changed in the last year.
