Retainers and Locks

Anyone have any input on some + .050 3/8 locks and retainers for four groove valves with typical 1.437 or 1.45 spring diameter? Comp says they have some available but I have yet to find the part number for them. Been through the search here but haven’t had any luck there either. Thanks Everyone!
I’ll go ahead and put a shout out to some of you who may know off the top of your head…

Four groove no but I never did a search for them.
