I just received a link for the appropriate tekst (Livy, book 44). A translation can be found here. Unfortunatly, it doesn't say anything about either chalcaspides or leucaspides beyond mentioning their existence.

Out of curiosity: if the histories did not mention them, how did you reconstruct the reformed pezhetairoi?
