I do not know what the size of the master clutch cylinder is. I'm assuming it's 'stock' Shell Valley Classic from 2003. I've contacted SVC to see if they can help me ascertain what the car originally came with. While I will flush the fluid I was pleasantly surprised to see all hydraulic fluids (brake and clutch) looked pretty clean...

It has a Wilwood slave cylinder. I don't know the size but Wilwood currently only offers one size (7/8"). Circa 2003? I don't know but I'm assuming it's 7/8". I have three master cylinders; one for the clutch and two for the brakes. (I'm assuming one master brake if for front and one is for rear).

The 302 motor has a steel bell housing / scatter shield with a stock looking clutch pivot arm. The slave pushes directly (very parallel) on the pivot arm.

I'm attaching pics. They aren't the best but access isn't exactly the best ...

Thanks, Dave K (Maryland)
