Okay, I have read numerous times that these drive shafs are crap on the Mark VIII's. I installed 4:30 gears and have a terrible vibration from 55-65, then from 70-80 a less but still noticable vibration. Anyway, I am going to have to surrender to the expense of the metal matrix drive shaft....but first I wanted some feedback on A. are they really worth the money, and B. where is the best place to get one...? Thanks, Derrick.
