Yes, we have.
Actually, A-35 system was not completed, so not all sites have to be symmetrycall. They just can be.

Well, now we have 6 reliable sites and 3 less reliable (SW-1b, SE-1 & SE-2). I still don't think that SW-1b is a missle site, its rather a command post or supply base. SE-2 also looks for me as a civilian production plant (it is situated near old opencasts). But... who knows...

By the way, the main visual features of the ABM sites is not a structure or shape, but a small round contrast spots - radar protective shields, or launch pads around them.
