Getting ready to remove a kmember myself and having never done it I will opt for the tool. Who knows, maybe it will get used a couple of times. I always find that the right tool for the job always works in my favor.....
Do yourself a favor and by some 5/8-11 all-thread - about 6" long, some matching nuts and washers. This will help you line everything back up when you re-assemble. They thread into the K-member bolt holes and keep everything aligned until you get the K-member close enough to use the regular bolts.
