I emailed a while back, month or so about this. I was told by George (?) that the G3R was going to be discontinued but that parts would be available for some time to come. He did not mention what was going to happen with the Maxx truck chassis. You might want to email them directly, they could probable get you what you need. Good luck, let us know what you found out. I just got a G3 chassis off fleabay, so I hope there will be parts available for awhile too.
