there is a npd parts down the street from me, i looked in their catalog but didnt see a m/c for the power disk listed so i was afraid they would try to sell me a wrong one, then i got one online from firebirdcentral.com because they claimed it was the exact one for power disk.. i thought about autozone or something but didnt think they would have one in stock or if they did that would have been sitting on the shelf for a long time.... that would be cool if you have something that works.... heres a few photos of the lengths. 67mm and 41mm thanks
