Plenty of other local installers have the case spreaders Any they often get made for much cheaper than $250. Now whether or not they use them or not is a different questions, something a potential customer should always ask when working on a vehicle that requires one (No Toyota's need them for example). However I can assure you many of the local long-time installers have them.
Yeah, Teraflex Plus has one. It's the one I looked at to copy when I wanted to make one.
