Unisaw replacement elevating locking pins

[Duke407]

Hi everyone! I'm new to this site and would like to first give a "shout-out" to all my fellow woodworkers!! My question is: I have a Unisaw 36-821L (left tilt) and the pins that "wedge" within the raising shaft/worm drive have become worn out. Can anyone tell me if all I need are the replacement "pins" or will I have to also order the pointer bracket that the pins rub against? Seems to me all I will need are the pins. I checked the pointer bracket and it looks fine (no wear/gouging, etc). Also, how difficult is it to replace these pins? I tried to remove them from the raising shaft, but they didn't seem to want to come out. Any advice? Thanks in advance for help!
