seems for every rule there is an exception: I was helping assemble a '68 Camaro my son-in-law bought in pieces when I noticed the driveshaft yokes were several degrees out of phase. I explained the importance of proper phasing and had him get another driveshaft. It was the same way! He took it to an old time driveshaft shop and they told him there was nothing wrong with it; that's how those Camaros came from the factory. I was working in a Chevy dealer's shop in '67 when Camaro's came out but never noticed this through the years.

There are two different levels of technology going on here! One is the Hot Rod level of technology that is based on fairly simple straight forward guidelines. The other is highly technical design engineering. These components work as part of a complete system with multiple interactions going on. Just because a design team of experienced engineers with test facilities can do something does not mean it will work in your garage. IMHO unless you really understand what all is going on it is best to stick to the basics.
