Just Dropped My Motor In
#18
for some reason the non-turbo series 4 mount is the most expensive one. Turbo series 4 is $56. It is probably worth it to get a brand new one just so you don't need to worry about it latter. I'd even get the competition Y-block mount to prevent side to side motion while cornering. Clunks and clanks from the drivetrain do not inspire confidence!

The mount only attches to the tranny through a rubber bushing type thing. The Y-block does not attach to it at all. The tranny has a threaded stud sticking out of the bottom which goes through the rubber bushing in the mount. There is no direct contat between metal with the mount and tranny. My car has a manual swapped into an auto and it has a custom solid mount which translates alot of vibration to the shifter. It is strong though, and never needs replacement.
