Thank you very much.

It appears that an version the precincts used to be available here: http://egov.cityofchicago.org/webportal/COCWebPortal/COC_ATTACH/precincts.ZIP

(There's some description of this data here, which suggests that it may be from around 2008, https://old.datahub.io/dataset/city-chicago/resource/14cdfd55-13a3-4708-ab3c-c862795f5c16?inner_span=True)

Do you have any idea if this old version of the egov.cityofchicago.org website might be archived anywhere?
