Anyone know where to find one of these??

Did you find this bolt? Let me know. We just stripped a 68 Barracuda and I might still have two of them. (the third is stuck with the head stripped). If you need them, I will give them to you.

The reason that they are 12 point is that they had to make the head smaller than the "standard" bolt, so they put 12 points on it so they can reach the required torque in the minimal space that they have to use it in.

I doubt that you will find this at your local parts store or hardware store. I'm sure that they had it specially made for this application by a bolt supplier.
