I grabbed a tray from tower that a member in the P2de forum used. Its model #103676
it fits, no real room around it but it picks it up out of the chassis for fresh air. I mounted it to the plate I had made for the original install but tape came loose a few times in fast rolls and dead stops. I like that it has a bracket for the on/off switch and the battery lead hold down. It site very secure after adding a thin 1/8 layer of trx gray packing foam.
I can see this working better if I pull out the dremul and modify the size of this unit. I like the switch mount and that its held secure and out of the chassis tub. Guess i'll carve it down to a better size and fit then update this thread.
