They all look the same to me.  I think that I have an extra set of springs and pins that came with a quick lock that I had.  I'll look...If I still have them you can have em.
I went through 2 sets before I switched to a spool.  Come to find out it was because I hadn't re-used the thrust washers...
But anyway...4wp replaced the whole thing for me under warranty.
Good luck
