as much as any good built 904. They are a 904 front half and the OD section is the same from an a500 All the way to a 48re add or subtract some clutches/steels depending on the model. You really don’t need to add a bunch of OD clutches as I don’t know too many with cars that are gonna beat on one in OD like the diesel guys do. However you can add a couple OD direct clutches (these are engaged anytime the vehicle moves minus 4th gear) very very simply by purchasing a 48re direct drum, apply plate and pressure plate.
