The L-6000 hole is slightly larger. I was able to get a 7/64" drill bit into the hole but not the OEM hole. I had to go down to a 3/32" drill bit for OEM hole. The upgraded adjuster also has a slight bevel lead into the hole.

You can also see the change in design. I mic'd both diameters and they are the same.
