The iconic Porthole on the
hardtop is probably the greatest identifier to the Thunderbird. The porthole is
part of the Retro T-Bird's heritage, along with the big round tail lights, round
headlights, egg create grill & the Thunderbird script on the corners of the rear fenders.
If the headrest of the passenger seat is in your way why not have the passenger seat moved forward some.
All hard tops no matter which year they were manufactured fit all the 2002 thru 2005 model years. Physically they are all the same size & shape. There is a few changes in the underside of the package shelf due to the shelf rubbing on the high folds of the
soft top causing wear spots and like pointed out above the water drainage along the windshield header was somewhat corrected. However, each top, in order to fit to the car body may need to have the mounting blocks behind the HT's windshield header adjusted. A very easy quick thing to do if needed.
The
soft top boot for the model year 2002 will fit all the 2002-2005 and the same the opposite way, all 2003-2005 boots will fit the 2002.
Also to Skizix Savage the color of your 2003 in the sales booklet is identified as Mountain Shadow Grey & the interior is called Saddle. Ford did not have a gun metal grey.
