Have done a search of the forum it appears that the 105 series cross shaft is larger and stronger than the 80. So my question is does anyone have a part number for the 105 shaft as the parts manuals I have looked at say they are the same part. In light of this should I presume that in fact the 80 shaft has been upgraded to the 105 and now this is the only one available. Any help muchly appreciated.
