Leading and trailing plugs... backwards.

Leading and trailing plugs... backwards.
I changed my plugs today for the first time since buying the car (about 4k miles ago). According to the paperwork there's only ~10k on the new motor which was installed by PFS. Anyways, the trailing and leading plugs were installed backwards. Anyone ever run into this before? Car seemed to run just fine. The plugs that came out don't look too bad. New ones went in the right way, will see if the car runs noticably better when my new wires come in tomorrow.

I got OEM plugs. They have a little picture on each of the boxes and say "leading" and "trailing" in big red letters. Pretty hard to mess it up.
I'm sure they were in there backwards. The 7's were in the top and the 9's were in the bottom.
BTW: if you do a search there is at least one thread on here where someone gets it backwards. The correct order (7 Leading (bottom), 9 Trailing (top)) is shown on page G-19 of the shop manual.
