wiper blades and arms

[boatman37]

well my wiper arm (and motor) is missing off my 1986 250DA. it apparently only had the wiper on the starboard side but i guess the motor quit and the PO removed it and put a handle on to manually operate the wiper. but the wiper blade is missing too. the arm is there but has an odd looking connector. can i buy a replacement at an auto parts store? i'm more worried about the aesthetics than i am the functionality but if i can find a good motor i would like to put it all back together the right way
