This time (2270 Raby engine kit for my 64 bus) I decided to design and have machined a 36-1 wheel to bolt onto the crank hub and be thin enough to sit behind the DTM pulley without needing any machining. Its the same outer diameter as the one i've been running on the speedster for 5 years but with chamfered teeth to match the angle of the sensor. The trigger wheel and sensor become almost invisible insitu.

The teeth are 5mm thick; thickness of the wheel at the hub is 2mm; its 115mm diameter.
Due to the cost of making just the 2 I wanted myself
