Empty out stockpiles of old obsolete weapons.
I would not dare use this junk as a primary. Big flash, lots of smoke, narrow engagement field, high probability of being defeated. This is old-old tech. If I'm risking my life, I want a chance to actually hit and take something out.

Set one/two of them up to make him react, and then send up the more lethal newer Stinger or SA-18/Verba with a good shot once he turns towards the SA-7 to evade.
My opinion, but I'm not an ADA guy. I'm just a has-been ground pounder.
The Strelas 1-2M already have a nasty reputation of exploding on launch when old, though - to the point where even the jihadis won’t use them any more. These are among some of the oldest.
