I'm pretty sure that at least the early cars use the same CV joint as our Porschii? We tend to have a real PITA on both the street and race cars with bolts backing out, particularly if you get CV grease on the bolts while installing. I finally said F it, and safety-wire 'em all... but now one of our guys is pursuing getting some made with locking tabs, not unlike the header lock bolt kits sold for V8's etc. Here's his group buy thread:

Is this of any interest to you guys? Reply back or send me a message...
