Finally someone did a good job taking pictures of a direct swap with an OFR, thank you a lot!
i have a yamaha RGX421D, its shape is like an ibanez Rg, and it have a japanese Lo TRS pro bridge, its not as bad as the TRS II bridge of a Korean Ibanez Rg320 that i had, but anyway i dont like it.
The RGX is fatter than the JS
type guitars so i think the OFR sustain block will fit too, if not i will change it for the Lo TRS as you did. (id prefer the original that is longer, better torque).
I live in Colombia so before i order an OFR i always wanted to see if it really fits or not and you did the work, thanks again.
by the way, did you changed the posts or you are using the ones that had your guitar?
