ALL the normally aspirated Subaru clutches are push type. They all interchange with each other, at least up to the mid 2000s, I understand. That is with the commonly used single mass fly wheel. All EJ series.
If I could get to a car or transmission, I would, if I could and measure.
I have a linearly actuating concentric hydraulic TO bearing. Before another one gets damaged I want to know what the normal TO range is for a stock application.
