Your '98 m90 has an updated design of the stop that keeps third gear in place and three-piece syncros.
The "synchro mod" has nothing with the syncros to do actually. And it doesn't really add any strength, it just makes it harder to break the part holding third gear in place on the input shaft
btw; I'm also running a holset @ 30 psi, it's quite fun!
