All the aftermarket replacements I Just looked at on RockAuto are crap to me. I know Todd's Old car and your new pride and joy.
Here is our photo shoot together. We live about 18 miles away.
Mine is a 94k gem. I still have the OEM rear suspension from the factory on the rear and it is tired.
I replaced the front with all OEM stuff with the exception of using a KYB GR-2 strut. It sucks. It is a worthless damper for the car. It is not what the OEM was. My father sold the car in 1994 and drove them and it is not the same. I am unhappy with the KYB unit from the first bump I hit and first turn I took without his input to boot.

This is a far superior choice than the units I see on Rock Auto. Names such as Gabriel, Monroe, Sachs are all I see for a 1992 Sentra SE-R, 2.0 Liter. Complete junk and nothing like the factory. And all factory units are Out Of Production. I tried that route on all four corners. They may exist but they are aging and in hiding somewhere lost in a parts department perhaps.
It sucks trying to maintain the car that is so old with parts becoming more difficult to acquire either being OEM or simply better aftermarket options because accepting worse than OEM is sacrilege.
