Would'nt it be easier using hydraulic calipers rather than cable ?, would just be a case of splitting the hose from the lever, Goodridge would probably do a custom split hose, need to be sure the master cylinder on the lever will shift enough fluid for both calipers though, also the Z1's are pre I.S, think Hope C2 calipers are your best option.
