Looking for LS7 Ballast/Trim Blocka

I recently purchased an LS7. On days when I eat only a light
breakfast, I'm awfully close to the lower limit of 165lbs for weight
and balance purposes.

There is a vertical post way forward near the nose that is set up to
accommodate a stack of 2.5kg / 6lb ballast/trim blocks, but these
unfortunately did not come with the ship. Does anyone know of a
source for these?

Thanks,

Jordan
