Torque converter bolts?..

I'm good, I went out to the garage and found another torque converter I have in the backyard and started doing some digging with my threads and taps. It's a 5/16 24... I'm pretty sure ARP is completely out, at least Summit racing is..
I think I can just Amazon some Mr gaskets for 10 bucks or something, they'll be here Tuesday no big deal..
So you're sure those are the ones you need? Sure?
