C2 w/s wiper linkage retainer part number

[John D.]

The retainer that holds the wiper arms onto the motor assembly under the dash The two arms have a spacer between them and then they are held on to the motor under the dash with a retainer.
Same retainer listed for 63 to 67. My 63 Aims= # 4766184. My 3/79 parts book list the retainer as 531848 (Group 10.160)
Is this part still available from GM? Is there a replacement part from GM that will do the job. I realize that I can buy a repro.
I assume that this part fits various GM vehicles but don't know.
Joe Lucia can you help please since this is your forte' for sure.
Thanks very much, John

GM #531848 replaced retainer GM #4766184 in May, 1975. However, the 4766184 remained available until July, 1981.

The GM #531848 retainer was discontinued without supercession in October, 1984.
