ok. let's start all over. the key purpose of the lunsford bits is too change shock tower positions in a few seconds by decoupling the shock "mount" from the way it's attached to the tower, so one can try shock positions in a short time without having to walk back to the pits - right?
as shown, the setup I use does the trick. Socket head, inverted shock bushing, (inverted in this case), 4/40 locknut screwed "backwards" - this is the "fixed assembly". then there is thread sticking out, this is equivalent to the short-end of the lunsford bit. This is what goes through the tower, and then another 4/40 nut secures it.
Now - granted, I can't leave the mount on the car and take the shock out indeed, this the $25 lunsford mounts do... But I don't really see this as an issue, when I redo my shocks, well, I leave the mounts attached to the cap, not an issue really... even makes things easier when you want to tighten them well.
Yes, I know, the lunsford bits and the RPM shock tool work well too... but they set you back $30
I'd rather buy two sets of tires instead
