Left = 18-spline | Right = 25-spline
This is the requisite plug for guys with FWD cars wanting to modify an AWD transmission, pull out the output shaft, and run it in their FWD car. With more and more owners doing the turbo conversions to their FWD cars, this is becoming a more prevalent modification simply because the FWD transmissions can only handle so much power before they pretty well blow apart. The AWD gearboxes are a lot stronger and can survive way more power than the FWD models. Once the output shaft is removed and the planetary gears are welded, this plug installs in the bell housing, plugging the hole where the output shaft used to be. Then the AWD gearbox mounts to the FWD block with no problems.
Select the model to fit the 18-spline or 25-spline AWD transmission.
