The part number is 600033 should be shipping next week and I'll have a price shortly.

Here are some pictures of my truggy and the setup I ran at the Quebec Classic. The truggy was pretty unbelievable the last 2 races with this setup. In the pictures I have the LR block but I actually didnt use that at the last 2 races. For the LW radio tray I used the speedo/servo mount and for the center diff I used the carbon plate and a nitro plastic cover ground flat to go over the carbon plate. For the receiver box I cut it off the old radio box and screwed it to the carbon plate to keep dust and stuff from getting in the receiver. With the alu servo saver I used the alu top part and the plastic bottom. The setup will also be on Serpents website shortly if you cant see it clear here. If you have any questions let me know.
