I can confirm that the following buses are still running (probably all on Rockland Coaches):
8704 (I have a photo of this one - also a former Lakeland)
8788-89, 8791, 8974, 8804, 8805 (Formerly Shortline Buses which were replaced by 17024-17041)
I believe (but cannot confirm) that I saw 8713 and 8755 as well.
As I see additional ones, I will make a note
