Badges,logos,etc for making custom decals

[Saturnine]

Hey guys I just bought a tamiya Efini Mazda RX-7, and I really want to make it into a type R. I've only seen this car in Gran Turismo 4, and one picture from a classified in Japan, but I didn't save the picture. Do you guys know of any website that has picutres of all the different badges, and logos from all makes of cars? I'm trying to find a picture of the "R"decal that sits behind the windows right before the hatch, so I cam try and make some decals. All i've found is the Mazda or efini logo. I wish it were as easy as finding a "Z/28" or "SS" badge. Any help is appreciated,thanks.

Oh yeah,,,if I do dind the pic i'm looking for, how would I scale it down?
