Roof height on 6” lowered OBS?

[Old 96]

Hi guys, can someone please measure the roof height of a 6” lowered OBS? I know wheels will make a difference so tell me which wheels as well?

I have 70” under my 4 post with my car up top so I was thinking a lowered OBS would fit under the car during the winter for storage.

I'm at 5/7 and sit right at 64". Hope this helps
