Yes, it looks like UUC has gone back to neoprene for their
"black" transmission mounts. Just another things to confuse customers IMO, as a couple years back the UUC black were neoprene, then they were black were poly, now they're neoprene again.
Resellers probably still have the poly in stock, and who knows when UUC changed, or what's been shipped.
I don't see on that link where they mention a new design--only that the option III (red track use only) is bolt through. IIRC the options I and II (red poly and black--neoprene or poly versions) were never bolt through. But they change the products around so much I'm not going to stick to that assertion too tenaciously.
I suspect Datastream has the poly. Easiest way to tell is that the neoprene looks/feels like very hard rubber; while the poly is hard, kind of shiny, and doesn't look like rubber. If they turn out to be rubber, the culprit probably is the "enforcer cups". These will cause an increase in NVH no matter what the dampening/isolation material.
Removing the cups and making sure things aren't over-torqued (easy to do since it's like 15 ft. lbs IIRC) might clear things up. Worth a shot if you don't want to spend more $$$, a PITA if it doesn't since install/uninstalls are a PITA to begin with.
