Broken Bolts on exhaust/DEF injector failure

Did you remove the DPF to drill out the studs or just drill them out under the truck? I'm asking because I'm at the same point with my truck. Also where did you get the replacement hose connector for the DEF line? I believe my connector is fine, but the DEF line will leak without replacing the partially melted fitting.
I'm having the same issue right now; sounds like 3/8" SS bolts are what you used? I will be making the trip to the store today.

I'm on the road at the moment, but I should be nearing 117,500 miles by the time we get back home. The truck will be due for an oil change, so I'll inspect the studs once again. I should probably wrap the DEF Injector/wires with aluminum high heat tape just in case the failure occurs when I'm on a longer road trip. I'd hate to scorch the wires and melt the DEF injector. I sure wish the studs would fail, though! My AEM warranty is about to expire!
