Hello,maybe I am wrong, or didnt get you correctly.
According to the documentation HR <> CRM integration, I have checked available docs here
https://help.sap.com/bp-crm#useful_links
Since you're asking for OrgStr setup for the CRM702:
1. Downloaded this DVD 50119922
2. As you mentioned in the beginning C05 Block is now related to the CRM Web UI for marketing...
Checked C01_CRM702_BB [CRM Organizational Model (C01)] and compared it to the old C05 version [CRM Organizational Model with ERP HR Integration(C05)].
I was able to find the same blocks. Not all is the same, but most of them are the same.
I didnt checked too deep, but looks like that C01 is mostly the same as old C05 (for sure sime units now have slightly another name, and some of them are move to the another place in the document), please correct me if I missed something.
KR.
