Mark , I appreciate your posting that information. I have to wonder about that stuff, and I am not trying to dispute science or anything like that, but how did we get away with spinning MP (that's Modified Production for you neophytes) cars to 9000+ rpm with stock driveshafts? I know that some failed, but for the most part driveshaft failure was not a problem. Every case I knew when a drive shaft failed was brought on by another factor.
Just wonderin', you know.
