Can anyone confirm to me that Tahu Nuva, Pohatu Nuva and Onua Nuva each came with a standard black ball joint for alternate builds, while Kopaka Nuva had three of those (for the Wairuha Nuva model) and neither Gali Nuva nor Lewa Nuva had a single one included?

I've almost definitely kept the piece-to-canister distribution throughout the years and the instructions only seem to indicate the use of ball joints for Tahu, Pohatu and Onua, but I wanted to ask for curiosity's sake.
