Here's a recent picture I took of a flywheel I removed from a 1984 944. Early cars do not have the mark that lines up with the notch on the bottom of the bell housing. The OT mark on this flywheel was very hard to spot so I made sure to mark it in yellow while I had it out. Below you can see the other notch on this flywheel that I am pointing to in the pictures. This notch only exists on the early flywheels. In the third picture you can see both it and the OT mark. I hope that helps!
