I am using a T56 6 speed transmission. I have a clutch mc/brake mc combo. Originally a line that pushes in and locks with a pin (line show in bottom in pic) was used to connect the clutch mc to the slave cylinder, but my new clutch mc requires the line to be screwed in to the back of the clutch mc.

the top line show in the pic is a braided line im using for the rear brakes (i just got it out to try and figure out how to do this). If i buy a new braided line i have the connection at the clutch mc figured out, but the slave I have still requires a line that pushes in and locks with a pin. Am I going to have to buy an aftermarket slave where the line screws in? do they even make them? help. thanks
