New antenna fit for the new AN/APR-25 RHAW system was the two disc-shaped antenna covers on the drag chute doors with the rear facing antennas. The Drag Chute door-107 was re-designed to accommodate the new antenna fit and the air vent profile on the door was changed from the original round opening centrally placed on the door to an upside down ' D ' shape lower on the door and under the center point. Since APR-30's was no longer installed from that point on the enlarged Door 621 on the left side of the tail was still present originally on many aircraft fresh out of the mod shop but gradually gave way to a return to the production standard door 68 as 1967 progressed.
