Here is a detail of the attaching plate. It is a composite of a 12 in. plate with the middle cut-out and welded to a 5-1/2 in. plate to match the electronics cylinder of the CI700 (the black device). The height to the top of the plate (bottom of the cylinder) is exactly 42 inches. This closely matches the original height of the field tripod - 43 inches - and works well for me, being 5' 7-1/2 inches. (Notice I got that extra 1/2 inch in there :O)
