Has anyone successfully used the USCartool A500 Crossmember?

Made some progress today. Finished my reinforcement hoop, and have it partially welded in.
Made an extension on the front edge with 1/8" plate, basically so I could weld to the top of the tunnel using the 4 holes in the floor where I drilled out the original spot welds.

Have it partially welded in, but have more welding and grinding to do. And I need to practice my overhead welding skills, cause I suck.
Sorry the last pic is a little blury, I was in a hurry.
