Many thanks for your suggestion, Chris.
One week later, and several phone calls to Lexus Customer Service, Lexus Edgeware Road and Lexus Twickenham and I am still no closer to finding what I am looking for.
The very helpful guys at Edgeware Rd even ordered the part numbers you suggested, but when they arrived, the kit contains 2 window decals for the rear quarter light (as you advised) and 1 decal that apparently fits on the front spoiler.
The problem is that the decals on my GS300 Sport are on the front wing, just below the side repeater (indicator lens) just behind the wheel arch. These are 17cm / 7 inches long and the same script / font as the ones on the rear quarter light. The ones in the kit are only 13cm long (and I do not have any decals on the fron spoiler anyway).
Can anyone tell me if their 300 sport has the decals that I am describing on the fron wing as I have looked at all the photos on autotrader and cannot see any there either?
Is my car really that unique??
I do have photos if anyone is interested, but do not know how to post them to the site.
Can anyone help??
