Have you drawn any conclusions as to what caused the crash ?
Now that there is a photo of the car 'on the wall' I didn't realise that you were so far down the track through the 'spill'.

I recall that you had posted about concerns with the car's stability some weeks earlier.
I have watched the YouTube videos of the car, earlier in the year and on the fateful weekend.
I am by no means an expert, but it looks as though the car was very keen to pick its front wheels up (possibly due to the heavy rake caused by the large rear tyres). It then tended to carry them but, at least on one video, drop them quite heavily causing a 'bounce' which seemed to unsettled it.
Any idea if the wheel drop was at a gear shift ?
The bounce then could have coincided with re-application of torque, further unsettling the car.
Plus, if as has been posted, there was a crosswind, especially from the left, you are out of the windbreak caused by the stands.
I think some serious analysis of your accident, perhaps based on your recollections (if you can recall any before the wild ride

More and more cars are getting faster and faster.
A 12 second quarter is fast.
By the time you have hit 10s, you really are in a racing car not a street car, and as such, it would be beneficial to move drivers more on to a race car mindset, where such safety equipment as you had in the Dart; cage, good helmet, good suit, probably some form of fire protection, should be almost mandatory.
Perhaps peer pressure from within MMA would ensure that members do take measures to ensure their safety. And not just for cars that could be considered race cars.
While the actual day, or the actual event, may not require the wearing of a helmet, common sense should make it mandatory, even for street cars. These old heaps don't have air bags, so even a bimble at 60-70-80 is going to involve a bit of bouncing about inside the car.
The much derided 'sleeves rolled down' rules are also thrown into some sort of perspective as well.
As the MoPar Nats are highly associated with MMA, it may be worthwhile asking the Nats organisers to make helmet use compulsory.
While it may be painful to do, I think a serious analysis (with photos) of your car would be useful, showing what damage it accrued, and/or how well it held up, along with a mention of what you think is salveable or requiring work to reinstate for future use.
Your crash has come as a bit of a shock to members (certainly me) and from the postings in the Santa Pod thread engendered a great deal of positive comment.
I think it is worth pursuing this to ensure all members safety while racing.
Racing has always been an MMA 'thing'. Many can take it just a bit for granted. But it is worth serious reflection.
All the best, and hopefully see you back on the track some time again.
