I checked the headroom for mine. I have 8' walls, and the distance from the floor to the bottom of the ceiling joist is 8 1/2' The highest point on my challenger is about 7 1/2' at the high point of the body line of the quarter panel at the door opening, though I made my rotisserie my self. Couldn't have imagined working on the car without it though, and I am planning on selling it when I am done.
