This is a funny thing. It seems to me that somewhere along the way, GM switched from the metal 'fruit can' type to the plastic ball type. Was this done mid-way during '70? I'm not sure. I know that my 1970 originally came the the 'can' type...but other trucks have the plastic ball type. Both are correct. But in terms of when the exact switch was made, I am not positive. It really depends on personal preference and the type of build you are doing. I personally like the look of that odd 'can'
