partsgeek has them in stock.
the Kyosan(?) OE replacement is out of stock (build date of 11/86); any experience with Beck Arnley for this?
i've got a kyosan in my '87 currently.
i also have a spare beck/arnley. it works.
i looked, they list 1 in stock. i'd be surprised if it didn't work for yours (my '87 has a build date of 10/86).
