In this book there is also some confusing about that. At first, Drozdov wrote that in A-35 system each launch node had 2 missile radars and 8 missiles (4 around each radar). Also launch nodes can be doubled - 2 LNs from different launch complexes at one site. Then he wrote that when modernized A-35M system was finished, 8 single launch nodes was built. He didn'r write about total number of missiles. Also, ABM internetional treaty in 1972 restricted the number of missiles to 100.
On the other hand, on fas images from Nudol site we can see that actually its a doubled LN with 2 target radars, 4 missile radars and 16 missiles. (See my previous post with ABM site description) And we can see at least 5-7 such sites.
