Does anyone know if it will fit in the recessed rout?
A link to the specific body would help, but if it's India-made, it will take an OFR. The older 90s Japan-made models with the Schaller-style short-barrel trems are the only ones that cannot take an OFR. Even then, it's an import, and parted out, so routing the rear of the recess is no great loss.
An OFR should fit a JT580LP rout.
Only the old JT6 had a different stud spacing from OFR.
i dropped an OFR into a japanese dkmg
don't know which LFR came with the dkmg
and the OFR sat about 1/8 inch closer to the fret board
