Though many wanted to see Earnhardt Jr.'s No. 8 follow him to Hendrick Motorsports, DEI owner Teresa Earnhardt, also Earnhardt Jr.'s step-mom, wouldn't give it up. The No. 88 has historical significance for the Earnhardt family too, though, as Jr.'s grandfather, Ralph Earnhardt, drove the No. 88 Oldsmobile back in 1957. The No. 88 was donated to Earnhardt Jr. in a selfless act by Robert Yates Racing, who asked NASCAR to transfer the retired number to Earnhardt Jr.'s new ride to keep the legacy alive.
