billet, I think this is the thread Art is referring to. Is this it Art?
viewtopic.php?f=3&t=31942#p177052About half way down Rockdaddy posted some videos, I think the 2nd vid is more what you are looking for.
Hope this helps.
cheers, jer
PS: the "chips" , ummmm, I'm imagining these are at the top front of the door area. Is this correct? At the firewall? Like the "frame" is bending in the middle. With 500HP and being drag raced is it conceivable that the front may have tried to come up, but without connectors or more cage the frame was suffering. And then when it hits the track again there is the opposite bending? Kinda up and down will have a serious effect on these somewhat weak "frames".
