I'm saying the thrust washers are made by Swift and SPL can get them for you. There's even a listing:

You just need to know the diameter of the springs Fortune uses
EDIT:
Do you have the SPL Mid-links? If so, those require 65mm ID springs (2.5 inch)
If you ordered from Fortune with a divorced set up, call the immediately and make sure they are sending you 65mm ID springs
Otherwise they may be sending you some 5 inch ID ones for the OEM bucket which will not work with the SPL midlinks
