tranny counterweight??
 

OK, I noticed on the automatic tranny it had a rubber insulated counderweight bolted to the tailshaft. (not the pillow bearing on the driveshaft!) i assume this is to absorb any drivetrain vibrations. anyway, theres a place on my 5 spd where it will bolt right up. should i put it on?? it weighs 5-7 lbs.

I plan on takin my automatic mount (interchangable with 5 spd mount) and filling in the gaps with window weld.

In case you dont know, window weld is that stuff that seals your winsheild to the car. once it dries its like a stiff tar.

really cheap alternitave to a nismo mount!!
