Thanks again for the input everyone,
Sorry about the confusion on the thread size and flats size. I had a pedal wrench when I was younger, 35+ years ago and remember that it was more narrow than a normal off the shelf wrench and it had a better grip and length for leverage. I went ahead and bought this Sunlite one:

For $12.50 and from the reviews I should be good. It will also give me 4 sizes basically so I can use it for other stuff (axle nuts?).
