Due to supply and demand, some the SR 32 X starters do not come with the threaded studs at the rear of the starter to attach the mounting bracket used on 85-93 900 models. Units without the studs are NEW units that Bosch also supplies to SAAB for their replacement needs. SAAB has approved the use of this NEW unit in place of the orignal starter. These NEW units do NOT require the use of the original rear mounting bracket.
