I still don't understand having to do this, unless
some module mount plates are older or dramatically different.
there is a Phillips screw in the bottom of the mount plate. you can see it before installing the pair of modules & mount plate in the housing on the rear of the left cam/head. this screw is hidden against the cam seal once the modules are installed.
on one end of the 3/4 module, there is one
small, black, Allen socket-head bolt like the two that are on the 1/2 module.
by loosening the Phillips screw & the single socket-head on the 3/4 module, it is possible to reset the position of it in relation to the mount plate. then you can move the whole module set & mount plate to the proper position for timing of 3/4. at this point, it is now possible to loosen the other two socket-heads on the 1/2 module & set it appropriately.
so, there is one extra step to the process if you cannot move the mount plate far enough clockwise to accurately set the 3/4 module to the timing mark. but no grinding should be necessary.
as I said, maybe some older Dyna-S mount plates don't have this "Phillips screw in the bottom" feature. I have two 5+ year old units, and two brand new in the last six months units. all four have it.
