There's a plastic ring at the top of the MGW shift boot with enough play in it that driveline vibration really makes it buzz.

Gary,
Wierd. My plastic ring presses/has tension against the shaft shoulder above it and no way would rattle or buzz.

I do "feel" the engine vibrate while holding the shifter, but don't "hear" anything at all. So its just the LTs hitting then?

Check the harmonic balancer, I havent looked to see what the Boss runs, but balancer issues are common with todays motors
