Didn't need to make a spacer between dial-movement because this strange rep had no groove/slot cut out for the dial, dial's just lying there stabilised by the spacer ring which fitted almost (needed to trim it to fit movement holder screws because the 2893-2 is thinner than 2836)
I know your problem but I solved it in another way with another project.
If you know the silver ring that goes between the movement and dial, just make abot 20 notches (no cuts) upwards in it so that it will be raising the dial.
very easy if you know what I mean,if not I'll try to find a picture
