I Dynamatted my transmission tunnel cover/behind and under the seats, but I get the impression that one either has a quiet or a noisy Bevel Box, and that's that. Mine still whines noticeably in Third and Fifth (in Fifth it comes in one the dot of 70 mph, which is useful in the UK in the absence of cruise control), but I have only done 1100 miles and I still hope that the BB will run in over the next 1500 miles. That's about half a week for you!
