The last Vortek seals I received were yellow and hard. Not sure if they have changed, I always like the slightly softer seals, but doesn't mean the Vortek seals didn't work. Good thing about a harder seal is under theory the lock up would be more consistent. I have been sticking mainly with the HW seals as they are very good.
Not sure I can help on the screw, other than I thought the HW 35 had the same style have you checked it out? I have dressed up several buggered screws in the past, clean the burrs and use 44/40 cold blue, turn out like new.
