Thanks for head up. According to the 72 Parts Manual, all A-bodies used the same wiper arm. That surprised me as the 23, 29, & 41 body codes do not use the same windshield. That said, it could have been a Trico or an Anco arm. It was the same part number regardless of body style. I stock Michelin and RainX branded refills. I'll check back later and let you know if the 15s of those brands are a full 15" end-to-end.
