Thanks to Dan Eberhardt for sending me this information via email. In Dan's own words and photos:

I thought I'd pass along this tool I made for loosening and tightening the 19 mm locking nut on the transmission adjustment bolt at the rear of the 5 speed transmission on an Eldorado. Due to limited access in this area with the transmission in the bike I've always had a tough time adjusting the pre-selector at the rear of the transmission so I bought a USD $6.99 Jetech 12 point 19 mm combination wrench off Amazon and cut the open end off leaving the overall length of the box end portion about 5 34 inch long. Then I ground down the sides until the width was about a 14 inch for about 2 14 inch from the backside of the box end. Once the locking nut is loosened I like to run the adjustment bolt all the way in and start my adjustments from there remembering to not go more than a little over a half turn out so the adjuster doesn't pop out of the shift return spring! The wrench works really well and makes this task so much less frustrating.
