Got tired of fighting with the universal adjustable spanner wrenches so I built one specifically for the 8-3/4. I realize you can buy them for about $40 but I had the materials to make one laying around and it took less than an hour. Still need to paint it.
Even though the main rod looks like a jack handle it's actually an old 5/8" diameter drag link from a lawnmower. You might also be able to use a old jack handle if it's diameter is large enough to accept 1/4" holes and still be strong. The pins going through are 1/4x3" stainless bolts that I cut the heads and threaded section off leaving just the smooth section. Drilled holes in the main rod, slid them through and welded them in place. They stick out about 3/8" on each side. Added a piece of pipe to make the handle o.d. larger so it's easier on the hand. Not only do I not have to fight the adjustable spanners to keep them adjusted right this is longer so you get more leverage to tighten the adjusters easier
