I was working on my Bronco in a friend's garage. With the door pulled overhead, he has just a few inches of clearance, but I got to thinking: What if he (and you?) backed the Bronco a bit deeper into the garage, then (taking off the forward panels first, of course) rigged a hoist (paracord + small pulleys should suffice) to lift the rear-most section? If you positioned the pulleys so they were outside the perimeter of the rear-most ("cabinet") roof section, you might have enough clearance to hoist it right up to the ceiling, allowing you to drive out, leaving that rear roof section pulled up tight to the garage ceiling.
To re-install your rear MIC section, reverse the procedure. Or, if you want to remain topless, drive in forwards, and the hood of your Bronco should fit comfortably under the hanging roof part.
A bit of thin foam attached to the ceiling would protect your MIC section of getting marred.
And you'd have to work out a system of lines and pulleys (and holding hooks?) so you can lift it evenly.
If you can envision my idea, the MIC forward panels would be stored in a safe location, and the rear-most section would be either on your truck, or pulled up to the ceiling and out of your way.
