Single Mass Flywheel with SB Stage 3 disc?

So I have the stage 3 drop in disc that I am trying to find time to put in. I just found a really good deal on a single mass flywheel and was wondering if they are all universal or if they have to specifically match up. I don't know the brand currently but I can find out if someone needs to know. Also are there any good pressure plates that will work with the SB stage 3 disc that can hold more than stock?

edit:

flywheel is a Spec SMF
