bellhousing clutch bracket replacement

I'm trying to get all the parts required to rebuild most of my clutch pivot shaft but all the kits I can find online seem to have a different style bellhousing side bracket. its 3 speed in a 73 if that gives any info. I just want to know if its something I need to have since the FSM doesn't seem to clear on its function. Thank you again for the help.IMG_20200326_123750.jpg
