Replacement DPad and Brace?

I recently obtained a PS2 with three controllers that all work, except for dpad issues. Upon opening them, I have found that they ALL have cracked DPads and/or DPad braces. I have no idea what they were playing/doing, but the controllers are all otherwise perfect after a deep cleaning.

Can anyone recommend a retailer/manufacturer that can sell me replacements for the DPad and the DPad brace? One would think that places selling the DPad would also understand that the brace behind it is likely to break too...
