Car: 1992 Subaru Legagy L 2.2L AWD wagon

There is a salvage yard in my area that specializes in foreign cars that
are over 10 years old.  For yanking parts off old cars, it's a good
place to go.  Sometimes I find what I want (and usually yank some other
parts while I'm there).  Depends if I find a match up on my car.  They
even provide a searchable online inventory of what they have in stock.
They include the date of when they got the vehicle (because I often find
after a couple weeks that the car has been already ransacked beyond
having any parts left that I want).  However, instead of looking for my
particular year, it would seem that I could search for a range of years
(that they don't let you search on, so I have to specify each year).

I have found that going to far away from my year results in slight
changes in the parts that make them unusable for my car.  One example
was a front fender.  Instead of having the squarish or trapezoidal
cutout for the side lamp (backside of the headlight), it was more
teardrop shaped plus the fender was 3/4" shorter.  Didn't realize that
until I had prepped and painted the fender and then tried to install it.
The salvage yard agreed to take back the fender although it was already
repainted and the salvage car was no longer in their stock which they
definitely did not have to do (a bit of smooth talking to a particular
gal there helps with returns).  They gave me credit instead of cash that
expired in a year so I found other parts to yank to eat up that credit.

For the '92, what year range could I use when looking at what they have
in inventory?  I don't know how much earlier in years, if any, that I
can go.  The fender fiasco was with a '94 Subary Legacy (but was
probably a sedan instead of a wagon and that might've been the real
cause in the difference in the header, or maybe some weird special model
that I don't know of that was offered at that time, and they do
differentiate between sedan and wagon in their online inventory).  Most
of what I want to replace is body or trim due to rust or damage and
these seem to be most sensitive to the year range of the car.
