Huh. I looked at a lot of control arm assemblies on the rear
of c. 1990 Hondas this past summer. They are not in big
demand. The biggest problem with them is that the bushings
eventually do wear. A lot of these little upper arms are
such that one can replace these bushings. Interestingly,
that's not necessarily much cheaper than buying the whole
upper arm.

Regardless, the site I linked earlier indicates that the
bushings are not readily available, or not available at all,
for your Accord.

You could go to a junkyard and I quite possibly get these
little arms for a song. I bought some for my 91 Civic and
paid something like $25 for two. Went to another yard a
month later and found them for even less. Kinda depends on
how much longer you want to keep the car, IMO.

Don't worry, they are upper.  I replaced this myself.
