Got the timing wheel installed. It’s a 60-2 wheel from Turbobandit in Sweden meant for the M103 crank pulley. I’m very pleased with this piece. It is the same thickness as and therefor replaces the balancer.
It’s a pretty simple process in theory but I had some problem getting the harmonic balancer of since I don’t have a proper puller.
