You'll be able to pinpoint the sweet spot position of the leaning post by just resting it on deck unsecured, moving it fwd/aft to find what's comfortable. Ultimately you'll want enough room away from the console to allow clearance for your knee's when sitting on the leaning post, and be close enough to the console so you're not having to bend too far at the waist to reach the steering wheel. If the console electronics access hatch faces aft then the amount of space between the console and leaning post plays a part here....the closer the leaning post is to the console the harder it will be to wedge yourself in between to work on electronics inside the access.
