Ok, all I can see under the bell housing is the pressure plate and flywheel. I cannot see if the disc . I can see that the TO bearing is in correctly. I am also suspect of the disc is in wrong. I read the stamping on the disc before installing (install this side towards flywheel)the extended center side. I had the original disc re-lined locally, could something have changed at their site? I guess it is time to remove the axle, trans and pressure plate to dble check
