OEM clutch slave hose, fitting details?

Hi folks, I've been working to get new hydraulic lines on 1010 but reached an impass regarding the OEM clutch slave hose connections. Anybody know what the correct parts are here? For some reason 1010s previous owner had replaced all factory parts with a braided slave supply hose which needed stacks of adaptors at both ends. I pitched the whole mess long back and never figured out how to do it the right way.

I'm fairly sure that the inlet to a stock slave cyl is 12x1.25mm. If that's how the stock hose is threaded, it must have screwed directly into the end of the slave, possibly with a copper seal ring(?). In not, what kind of fitting or adaptor is used there?

Same question for the other end of the hose - what are the threads and how is the connection to the copper hard line accomplished?

Anybody have photos of these details? Specs on the OEM hose would be fantastic as well, especially length and end fittings.

Thanks for any help, it would be REAL nice to hammer out this detail and move on to the something else, hopefully not in the hydraulics dept Regards, Nate s
