seems like it, get a good branded battery terminal (SNA make them) - now find good quality automotive purpose wire, cut it long enough for it to reach the starter mounting ear neatly, now peel off some insulation from the middle of the wire and make a branch of to attach to the body of the car, Solidly crimp lugs onto the wire ends. (best ground cable)
Do not use oversize wire as it may hinder current flow.
