Word round the camp fire was that the rear locked up.......no idea as to why.
We learned the hard way about trying to use a stock drive shaft very early on.
On street tires , it spun hard into third.
When it finally hooked , it twisted the shaft in half , shelled the trans case and beat a hole in the floor behind the front seats.
The loop did it's job.
And I could see that being a contributor to this one.
It could have been so much worse.
