The Energon Pub

All i need is the knee caps, the removable antenna, and some parts for 6 shot...It is worth it because i have the original metroplex with the rubber tires and chrome legs!

Eh sorry, I don't have anything, but have you checked eBay or Wheeljack's Lab? Those are fairly common parts, so they shouldn't be too hard to find or all that expensive.

Transformerland.com is always a good place to go for parts.
