I got a Mad Dog Stage II ready to go in (thanks Elliot). I got 2 -Six Shooter Couplers and I want to use new bolts on them but I'm unsure of what to use - suggestions?

I don't know.
But let us all know how the trans works out!
What mods were done inside it?

If I remember right the stock bolts are a metric 12.9 which is better than a grade 8, so they are pretty strong bolts from the factory. I'm not so sure you can just hop over to the local hardware store and pick something up that's stronger. I've seen 12.9 at my local Ace hardware, but that was as high as they went.

You may drop ARP a line and ask them if they had something.

Can I just reuse the bolts from the old couplers?
