Simpson Lawrence windless Gypsy

[SV dragonfly]

Looking to find a new gypsy for a S.L. Sprint 1500, currently it is a 3/8 BBB chain and I want to replace it with a 3/8 G40 or even a 5/16 G40 anyone know where to find the replacement parts beside SL spares

Other than SL spares, I think there's only ebay.
