2-post lift attachments for lowered cars?
 

So I want to either swap out the arm extensions on my lift, or modify the current ones, so that I can fit the pads under lowered cars.

This is what my current arms/pads look like. The smaller square tubing that slides in and out of the arms is 3"x3" and the lowest pad height is 5.5".

I found this photo on the net, but no link to purchase. See the bottom example?

Anyone here have the skills to modify my current arms to relocate the adjustable pad lower? Maybe someone @digital_assassin knows?
