It felt like it was right under the middle of the car underneath, where the trans is (duh) but also the big joint in the OEM driveshaft.

After upgrading to a DSS shaft, never had another clunk, so for me anyway, the source was the OEM shaft. This sucks that the factory couldn't get it right and some Boss owners shouldn't be forced to spend 700$ to upgrade their shaft. I always knew I wanted one in my Boss from day 1, and it was in my garage waiting to be installed before my car was delivered.

YMMV
