Are the "Those Things", "Pucks", or "Pits" still available?
No. Those became the LM Pillows, Discs and Curved Shelves.
DJ Casser passed away back in 2012 and I think, (although I do not know for sure) that the audio side of Black Diamond Racing is no longer. The family kept it going for quite awhile after his death. Music Direct usually has lots of BDR stuff and they don’t have a whole lot left.
The website is still up, but hasn't been updated in awhile.
Maybe someone knows for sure?
