AN-PRD 2 radio detection finder pictures

Post by Johnsamschulz » Tue Apr 13, 2021 11:54 am

The museum at Fort Huachuca Arizona is planning to have a static display of the AN-PRD 2 radio detection finder mounted on a 1965 M151A1. Does anyone have any pictures or Army TMs showing how the AN-PRD 2 radio detection finder was mounted on the jeeps? Any help would be greatly appreciated.
