Awww man, now you're just showin' off. Nice shop!
By the way, do you also import and/or have you tried the AC Hydraulic Autolift
That jack hole gizmo is cool, and reminds me... someone (here?) had made some rods out of thickwall pipe, bent slightly, so that when inserted into the jacking holes they stick out horizontally. They can then be cradled nicely in a saddle-type jack stand.
Kind of a slick solution other than having to pop the hole covers off all the time and maybe wearing them out. But I'm not sure I'd be completely comfortable with it as the stand isn't directly under the load. I don't know if it'd be more or less susceptible to shifting, but either way if the pipe snaps, yer a goner.
