You need to differentiate between 'straight cut' & 'Dog box' Solarfilms

Straight cut & helical are gear teeth profiles

"Dog Box" refers to dog engagement rather than easy to drive Synchomesh that you have now. They are very different animals.

1St & 2Nd synchro straight cuts were a popular choice - they cannot be flat shifted though.

Dog engagement boxes are best left for race cars.
