New commercial mount for 2004R transmission
Just some updates;
1. The new crossmember and transmission mount, to install the 2004r in the Mopar A-Body, is now in production, link to the details:

Thanks for everyone who commented, suggested and in general supported this upgrade.
2. The new T56 is on order. We went with the .5 overdrive version, so Chris expects to run a 4.56 rear (yep, that is steep!) and cruise on the highway with 28" tall tires about 1750 rpm at 70mph. That is pretty street-able. Also should be a crazy autocross car and that is what he is building his Dart to be (This is Chris's Dart, not Jeff's dart which has the GM automatic. - subject of this thread). Should see the replacement floor tunnel and perimeter frame in about a month after we receive the T56.
