2005 Sabre style dash, 8″ or bigger Graph

I have a 8" and 10" HDS gen 2 (non-touch) ready to install. I was wondering if the 10" is too big to be mounted on this year style dash, in front of the steering wheel? Should I use a Sherms mount, or one of the newer mounts available? Anyone have pics of a bigger Graph on these year boats ? I assume flush mount will not work with the 8".ThanksForgot to mention my current setup is a lms-520c in dash and a hds-7 on a ram mount on the handrail.2005 Sabre, 150 XR6, Minn Kota Fortrex with Lowrance electronics
