AlV 69 Dodge GTS project

Really like the lift. Thinking about doing something similar in my garage. How much floor to ceiling clearance do you have to accommodate the lift? And did you install it yourself or have it professionally installed?
It's a mid lift about 48 " on standard pads but I als have 3" and 8" adapters. It works perfect for standard garage ceilings. Hi enough to get a roller chair comfortably underneath at full height. With 6 automatic locking positions you have lots of flexibility.

I installed it myself in a few hours. Hers a pic of me doing brakes on my wife's pilot. If close the garage door I can go up another 12"
