The tool is J-29724 and it’s nothing more than a simple turnbuckle. No idea on where to buy one but if one must go this route then I would think it could be easily fabricated. It simply pulls the top plate one direction or the other.
A pry bar should work as well and one wonders how in the world “one of the best alignment shops in Orlando” is aligning any of the millions of these cars on the road.
Maybe you should ask them if they’re adjusting the toe and saying to hxxx with everything else.
Strike the word “best” from the description. 
(One of my son’s cars is an 88 Camaro (same thing) and alignment adjustments have never been a problem; either at home or on the rack.)
