I'm not so sure of the years but in a few years the pumpkin was aluminum! There seems to be a lot of failures in the 44's with the aluminum centers. I understand that mopar stopped that at some point and went back to the cast iron centers. So the advice you'd get here would be to stay away from the aluminum ones and the iron ones are good as gold.
