Perhaps you won't find them this way. Try to visit bilal ganj in Lahore, locate any good shop for honda parts and tell him that you need door glass weatherstrips complete with clips/retainers. Most probably, you will get these free in the price of weatherstrips.
When the seller ia removing these strips from the doors tell him to be gentle with the retainers as you need them unbroken because the ones installed in your car are also damaged or missing.
You can utilize the new weatherstrips as well if existing ones are not in good shape.
