Unique class for listing and property details pages

Hello.
We want to exclude some module appears in those pages .
At the old OSP we have found that the property details page has unique class property_details so we have use:
body.property_details #rightblock {display:none;}
And for the listing page we have found the unique class : ltype so we have use:
body.ltype #rightblock {display:none;}
BUT now we cant find a unique class for those pages , so we cant manage which module will appear or not on those pages .
Thanks
