Hi,
Recently got one at Autozone:
   CST 6808  Non-locking Fuel Cap   $9.99

I got it at a store here in Chicago, but it also shows in their on-line
catalog, autozone.com

When I bought my '91 GL about 8 or 9 years ago, there was a rag stuffed
in where the cap should be.  I went to the dealer and got the locking cap.
   After a few months Vinnie and I were summoned for his emissions
testing.  They tried various adapters on their computerized gas cap
tester but none of them sealed correctly.  Finally they called the
manager over and he gave it a "visual inspection" and pass.  This same
process was repeated at each inspection since then, every two years.
   This year I decided to save some time and hassle and bought the cap
described above before going for the emissions test.  We passed the dyno
test very easily and got a "Quick Pass" after only about a quarter of
the sequence.  Went down to the end of the line where they print out the
certificate and the guy said "You have to go to the office.  Your gas
cap failed."
   I told him that the cap was only 2 hours old and expressed my opinion
about their testing equipment, but I still had to go the office.  The
woman there looked at the cap, listened to my complaint, put the cap on
and off the van, fiddled with her computer for a while, and gave it a
visual pass.
   Oh well,

Larry A.
