Here are some pics I was referring to

Picture of the Trackick upper mount and lock washer and the cut plate. The outer figure of the plate still needs trimming to make it a little neater along with holes drilled. 6 holes will be drilled, 3 for the Trackick, and 3 for the XL7's strut mount. I don't have an XL7's upper mount free to add to the picture, I'm currently using both of mine.

The idea of the Trackick mount bolting from underneath. It's kinda high here in the pic due to the studs which haven't been pushed out. But the Trackick will be bolted to the underside of the plate.
The XL7's will be mounted to the top of the plate. The bolts securing the XL7's mount will be longer and there will be a small spacer between the plate and the mount. This is due to the nuts holding the Trackick bolts. Also, since both mounts are triangular shaped, I'll offset the holes.

Gives the impression of the offset. The XL7's will be drilled into the larger corners.
What this will do is keep the XL7's mount in its stock location, thus use the stock cross brace support.
