Thanks! I stopped by my local dealer and they said yes, I'll need it -- but they're also interested in selling me one, so I gotta question their honesty.
I think I'm going to take my chances and see if I can get it to work -- I need to read through the manual one more time and look over some videos that hopefully have suggestions. Thankfully I have a buddy who's a much better wrench than I am coming over to help.
Thanks!
