Not a selectable, but I have a 31 spline 8.8 Lockrite that needs new springs (~$10 from Richmond Gear) that I'll sell cheap. $80?
It has a slight nick out of the outside of the case where the one of the springs goes in, but it doesn't affect functionality. I can take pictures of it if you're interested.
