Installing A 6inch Setback Jackplate

[TS Nitro]

Hi everyone, I'm getting ready to install a Jackplate with a 6 inch setback. I own a 1994 Nitro 180fs.
The question I have is will I have to get longer steering cables or will mine be long enough. It looks like im going to have to reroute the cables the barley fit out of the factory hole now.

Thanks
Nitro
