Steering link arm for 1977 johnson 55hp

[scott_maier]

Hello,

I'm putting a bare bones center console on my boat and i need to set up a new steering system. I'm new to this but i think i just need the cable, helm and that link arm that goes thru the transom mount bolt. I believe the cable is standard, but I'm not sure about that link arm. I was wondering if anyone knows where I can find the right part number for the link arm or if it is a standard size for many motors. The motor is a 1977 johnson 55.

Thanks in advance,
s
