Maybe the rear suspension was a factor in what happened, maybe not. Perhaps
we'll never know. 

I'd still avoid a swing axle if I were building a new car, though.

well hard to argue with success,  for over 40 yrs it
set more records than any other car,  put more people into
the 200 mph and 300mph clubs than any other

Hmmm...I sure would avoid using one of those types of rear 
suspensions-- swing axles are treacherous; they exhibit large camber 
changes and their jacking effect almost guarantees that once a certain 
point is reached, a driver can't save it. About the only way to make a 
rear swing axle manageable is to limit the wheel travel to only a small 
bump & rebound.

Glen:
the 77 had a lot of positive camber showing on the rear when I saw it 
towing to the line in 2001.  I pointed it out and somebody told me it 
w

as a swing-axle.  I met Seth, Tanis, and crew later that week (we were 
next to them in Impound),  and I think I remember discussing the rear 
suspension with Seth, or maybe one of the crew.

Have they changed it since then?
