What have I got
 

Hello
I am trying to determine what type cv's I have in my 914. I am using a 901 trans that has larger diameter drive flanges The bolt pattern is about 3.5 inches center to center. I have 5 bolt hubs with what looks like vented 911 rotors. I am trying to find what cv gaskets I need.
Thanks
David

How many bolts on the CV's? That's how you tell what shaft you have. Indeed, the hubs and splines themselves could be early 911, but they use the same drive shaft pattern.
