I"m working on a 71 RR with the A01 light group. Apparently they are still available for my car as well as for mini vans made up to the 90s. They are one and the same relay. Part # 2889565. When I ordered the relay from Southbank Dodge Chrysler, the part even came in the old style Mopar red and black box. Which just goes to prove that NOS parts are still available at the dealership.
