They aren't "mistakes' per se. They are just staus quo technology and engineering for 1970.
There wasn't a lot of point into making these cars handle like a race car simply because the weakest link in the solution is the lack of capable street tires.
Average street tires today out perform race tires of that era by a long shot.
The reality is that the modifications necessary on this vehicle to bring it up to current technology really are kind of moderate all things considered.
That alone speaks for the design considerations from 1968?
