As we all know, not all needs are answered by over-the-counter tools. As one example, my Z-friend Dieter Roth made his own special wrench for one particularly annoying Z job (halfshaft U-joint bolts, IIRC) by simply grinding off the excess metal from a standard open-end wrench so that it would fit inside the limited-clearance space.  For my own efforts, I've enjoyed constant use over the years from a 18" length of 1"-dia aluminum tubing (from a TV antenna mast) that I squashed one end of so that it would fit over the end of open-end and box-end wrenches to give extra leverage.

What's in your tool box?

You would think a substitute could be found if a bushing mfg catalog could be looked over. We still use this kind of bushing in all kinds of modern applications.

Were straying way off topic here but finding a bushing that is already in production that fits is probably the all around best solution.
