The answer to this question is “yes”. You can use a 36in a bar from a STIHL 661 on a 3120 Husqvarna. To do so, you need to modify the tail of the Stihl chainsaw. To do this, you need to make the mounting slot wider and drill new holes. You will need a milling machine or drill press to make this modification. Below are the different combinations of bars and their compatible features.
