I brought a push pull convertor to suit my r34 box, (os giken clutch) Upon install the bearing carrier is way too long for my application (turns out its getrag carrier, god dammit), and its hard up against pressure plate. Anyway I was wondering whats a suitable clutch throw, would 5mm be realistic or would I need more. As you cant buy the convertor carriers seperately so Im told, So im stuck machining this one.

if you are saying 5mm at the slave then no 5mm aint enough

I mean between the bearing and the pressure plate.
