What do you guys use for hardware whenever you replace a D1's Rear Upper Shock mounts? I had one mount that snapped off, so I'm installing the TF 2" lowering mounts. The existing hardware on the truck is wrecked (threads crusty to the point of having to cut some of them off).

It looks like they're supposed to be M10x1.0x110. Finding that specific size is proving impossible locally, and even McMaster Carr doesn't seem to have it in a grade 10.9.

Any reason you can see that I wouldn't just to go to a 1.5 thread and use a locking nut?
