I need to replace the Clutch in my 79 z with a factory ST10 4 speed, what size and splines do I need to order? Summit lists a 10.4 inch 10 spline and a 11 inch 26 spline kit. Not sure which one I need, and Id like to have the parts before I take it apart. Thanks,
I'm definitely not the expert but I believe you will need to pull it to verify. I got mine used from an 80 Z and it is a 26 spline model and the replacement clutch the guy gave me was a 10.4 in, 26 spline. I ended up using an 11 inch though. Not sure how much this helps but, for what its worth.
