I have found 1 OEM rear spring (Honda # 52441-SP0-G01) that fits your vehicle.
I found it on Mercari app (please see attached photo).
If you're not familiar with Mercari it is similar to Ebay and you can download it for Android and Apple.
I also have attached a photo that shows this Honda/Acura part fits 1991-1995 Legend Sedan/Coupe with either a 4 speed automatic or 6 speed manual transmissions.
I hope this helps!
