I have the BBM to T-56 scattershield in my storage shed -
The T-56 / TR-6060 should have the same bolt pattern to physically bolt up the the same bellhousing... the issue is that various T-56 and TR-6060s have different input shaft lengths... I couldn't find any specs on the Dodge TR input shaft length - but the that is probably why they list the 8073 as not working with the TR-6060...
I actually have a Viper spec T-56 for my Charger and the input is longer than the GM and Ford input shafts so I had an adapter plate made that mounts between the bellhousing and the trans to adapt the bolt pattern and take up the space.
