No, a 1982 Jeep DJ-5 (Postal Jeep) hood is
not the same part as a 1973-1986 CJ hood. The DJ-5 and CJ series Jeeps, while both Jeeps, have significantly different body styles.
You cannot use them interchangeably. The dimensions, mounting points, and overall shape are completely different. A CJ hood simply won't fit on a DJ-5, and vice versa.
