stock 340 valve spring retainers

[Valleyant]

Are stock valve spring retainers the same for LA 318, 340, 360? I need a set for some 340 springs that I have. If so, where is the best place to p/u a new set of these? TIA

The retainers are all the same, I would not buy new. I would buy new hardened locks though. I have a set of used ones if you want.
