200R4 update

Some food for thought. I have done a bit of investigative work on the 200 4r setup as well and found these guys in Cincinnati. Seems like they are up for the job as well. I know everyone talks highly of Art Carr but I am sure he's not the only one who can build a good transmission.

I have never done business with them but I plan on checking them out when it comes time for the tranny in my project car.
