I graduated West Coast University in 1982. They have been closed since 1992, where can I get copies of my transcripts?

Start with the State Board of Education

There are at least 10 universities using some combination of that name.
West Coast University, (google that name and fraud) and you will see the most famous one was not accredited and considered a fraud. They are even on a "black list" of schools not accepted by almost anyone.

If that is yours, there is no records for you to get.

If this is another school of same name, and they were accredited, the Dept of Education for that state will have a copy of your records.

If they were a non accredited school, there are no records to get, if they are closed.
