Blalance driveshaft
#3
There is a specialist driveshaft shop in western Long Island, I forgot the name, but all of the good performance shops in the area use them. Dave at Cartek knows/deals with them. Most of the local shops near me will not even consider a balance on an Al alloy driveshaft, these guys fabricate racing ones.

well when i am cruzing on the highway i get this small vibration by the shifter. when i punch it, the vibrations get louder and you can feel it a lot. mostly in the front. it cant be the tranny bushing cause i changed it with a poly one last summer. any ideas???
