More helpful info:
www.norotors.com it seems to be new source since v8rx7 is down.
These two names:
Samberg and Pez.
Samberg is a fabricator who makes some great pieces for swaps if you don't like what Hinson sells. I don't think he has a website but he can be found on the norotors forum.
Pez is Eat Pez from rx7club. Pez is also a fabricator but also specializes in wiring and a/c conversions for v8 rx7s.
Both are helpful and seem to be the reigning autorities on the subject.
Knowing what I know now, I would have likley gone with Samberg's subframe and tranny mount.
Brian Hinson has been nice to deal with and has been very helpful whenever I've had questions.
