Ok, lets do this like this. When Penske/Jasper did my rebuild they told me not to use the existing pulley I supplied with the engine. I found a pulley/dampner on Ebay that according to the supplied numbers is for a 92 series DD. I noticed the dampner was missing from the ad. So I emailed the seller and he said that was an accident caused by one of his employee's and apologized for the error.
My question is what should I look at when deciding whether a pulley is usable or not? Penske/Jasper said the supplied pulley was pitted and not considered reliable. Which is fine with me. I'll just find a new one. Which it seems is the one I've located on ebay. I just wanted some input one the pro's or con's of pulley science.
I've posted the ebay page: http://www.ebay.com/itm/290771750277?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649
As always input good or bad is appreciated, its my job to filter the information. LOL
