Alright so Im thinking of buying an s2k cmc for my ek. I understand I need the spacer, but I see people changing there clutch line, is this because the fitting in the s2k cmc is of a different size then the stock ek one? If it helps, I have a k-swap and my clutch line is already stainless steel.

could a mod delete this, im moving to another thread
