Need a pole to lower the spare tire on my 2004 F350. This tool worked, but not without making some changes. Other reviews said they only used a 3/8" ratchet on the end to drive it, the tool I got had a 7/16" drive. So I had to cut out a 1/2" extension to fit the 7/16" disc. The other end didn't fit into my anti-theft outlet, which also required some grinding, drilling, and a locking pin to keep the outlet from falling into the conduit. Other sizes may be available for specific applications, I'm not sure, but the time it took to get this tool working for me I could easily do it myself.
