These are correct (except for the most minute details) for ‘68-72 A bodies. They’ve been ‘on again/off again’ in their availability. What’s really weird is that they don’t come up in the catalog search (except for ‘68 Grand Prix) but the old Trico paper catalogs list them. Some of our other cars take an 18” blade, it’s 33-183 and it looks like they stock them, too (Also not by application). Good price on them!
