The completed and reinforced mounts. I still need to weld the captive nuts in place with the TIG. I don't trust my small MIG welder to make strong tacks. On that note, I used the Miata V8 Blogspot posts by Mike Moninger to come up with these designs, but I modified them to have accessible nuts even if I will be welding them in place. I don't like enclosing captive nuts to where they can't be serviced. Especially since the distorted nuts wear out eventually.
