Thank you, sir.... I appreciate the kindness very much!
Those third members just seemed to get heavier and heavier every year. sigh...
I needed a "cheater"... so, I figured this was as good as I could come up with.
The only modification to the (cheap-***) Harbor Freight transmission jack was to drill two 3/8" holes in the top surface to keep the part I built from sliding around. I just put two bolts the top part I built and ran them down into the platform of the jack, and it's solid.... no unwanted movement.
