drive shaft loop

I was unclear as to whether or not I was supposed to have one with drag radials. I figured it couldn't hurt so I made one at work today.

That's a good looking piece, Bill. Don't think it's required for dr's, but if a tech thinks so, you might be screwed. It's always a good idea to have safety pieces on your car.
