The screws that are upside down that hold the small flat plate that goes from chassis to trans and connects to the main body of the tower, both of those stripped completely. I was able to use some longer bolts and nuts to save the tower but it was still one of those "how the hell did i do that?" moments. In hind sight i think those screws backed off a little bit without me noticing and when i slapped the ground coming off a jump it was loose enough to gain the momentum needed to rip the threads. Front one is still doing good though.
