Hello P Schaub,
Looking at the options available to you for parts...
Published by ROCKAUTO...
- it does indeed seem to be YOUR CHOICE...
Either TYPE of BULB seems to fit your vehicle .
Still LOOKING but I see no RESTRICTIONS.

But will the whole tail light assembly from mercury grand marquis fit directly in my 2005 mercury Montego? Would much rather order 2 new marquis tail lights then the 1 Montego tail light since price difference is better.

Sorry.. I miss-understood.
I thought you were trying to save (avoid)the $20 of the LED over The old style... .You are seriously wanting to use Crown Victoria "housings"...?
If I am understanding ... you want to reconfigure your back-up lights & everything?
Sorry I got in the way of this question. I would NOT recommend downgrading to incandescent...
but your are talking custom wiring as well.
I would not recommend either. The dealer cost for each Crown Victoria is over $100 each... and you HAVE NOT EVEN started with the CUSTOM WORK NEEDED for our reverse (back-up) lights.
I absolutely believe the trunk lid is different as well...
If you want a sheet metal guy to tell you the
fenders are the same... The best recommendation would be to RE-POST your question. I'll steer clear. Sorry I miss-understood your objective.
I would suggest your repost. http://www.rockauto.com/en/catalog/mercury,2005,montego,3.0l+v6,1431204,electrical-bulb+&+socket,turn+signal+lamp+bulb,13675
