Schaller R4 locking nut for MIJ PS4

[tanpsi]

Has anyone installed an official Schaller R4 locking nut on a MIJ PS4? Were there any issues other than the height of the R4 nut? Did anyone get the nut machined down instead of deepening the wood shelf on the neck?

Thanks,

Could I ask this again in the tech section?, or move it there?

Thanks,

Edit, sorry I forgot about the Google search that lets you search for r4, so i found info using that
