Thanks to all for great the information. SHO Source has the connectors available.
Mike from SHO Source also sent me the forum link on installation;

A few notes I want to mention:
- Our subframe connectors are thicker steel than the ones in the picture (stronger)
- Our subframe connectors have a beveled (angled) leading edge that is capped. This not only keeps debris out, but it also helps prevent the connectors from catching on things (road debris, speed bumps, the subframe in a catastrophic crash, etc).
- I recommend 1” welds rather than ½” welds, but I do agree you want to stitch weld rather than seam weld.
- I cannot emphasize enough to be careful of the fuel lines on the passenger side. I personally pull them away from the unibody and wrap them in wet towels to keep from melting sparks into the plastic.
