What size bolts on catalytic converter?

[Carlo]

Hi all,
Last night on my way home from work my 2014 1500 v6 started sounding like it had an exhaust leak. So just now I went and looked under my truck and I could see a broken bolt where the leak was coming from. It's where the catalytic converter attaches to the the exhaust pipe. Does anyone know what size bolts these are?
I won't have a chance to jack the truck up today to figure it out and I will be going out tomorrow morning and ideally would grab some new bolts on my way home, would save me a bunch of time if I could figure out what bolts to buy without having to get under the truck.

Any help would be greatly appreciated

I don’t know the size - but you may want to stop at or call a dealer, as they may have the common bolt in stock (it may be a special bolt due to the connection and heat).
