I think you have to replace the entire assembly unfortunately. I found a site that sells the assembly used, I got a brake booster from them not long ago and they had one at that point.
Thank you both for the suggestions. I will check out the link and or reach out to Woody.
After some further inspection I noticed it's secured with rivets and I can't tell if the rest of it is removable. When I decide to fix it I'll take pics and share. I'll have to deal with a jenky hand brake for now.
