rollerize 904 help

looking at maybe rollerizing my 904. does anyone know what thrust bearings are needed, do you only rollerize the gear set or do you replace all the thrust washers with thrust bearings.
pictures of any machine would done would be helpful to.

thanks

The original babbit washers are WAY tougher than Torrington bearings.
That said IIRC they make them for some places in the trans, but not for everywhere there is a washer style.
Only for the front drum to pump stator, one side of the planetaries and reverse drum to case I think.
Been a long time so maybe more now.
