1958 11 AFAC (Clipper?) Need Incabloc Parts

Hello. This is my first post to watchuseek, and I'm hoping someone can help me.

I have a Bulova 11 AFAC which I believe is a model "Clipper", from 1958. It uses Incabloc at the balance wheel shaft pivots. Both the lyre-shaped spring and the jewel(s) are missing from the top side. Does anyone have these parts? Or, alternatively, does anyone know the Incabloc size for this location? I can find Incabloc assemblies all over the net, I just don't know what size to look for.

Thanks!
