In the Xmods section here there was a Chrysler 300C Kyosho body done on an Xmods that I thought looked cool. You may have to search around there.
The nose mounts are about the same, just that the Kyosho or Iwaver uses a different mount for each body. So getting that to line up with the Xmods clip would be tricky to do. In some cases you might get lucky. I would guess about 9 out of 10 you will have to make your own tab to locate the front section with. I am not sure how good it works, but I have seen some Kyosho nose clips modded to work on an Xmods chassis.
The Kyosho and Iwavers use side mounts that attach to the notches in the battery holders at the sides. The Xmods use a rear mount so you will most likely need to scratch build that. Or as the thread on the 300C, he said that he cut down the side mounts and fit them between the batteries in the sides.
On
Xmods with MiniZ board there is a thread on an Xmods with a Kyosho board that also has an Iwaver body in it.
Here's another thread, but not much to it.
Here's that Xmods 300 C thread.
