Could you tell us more specificly what you're looking for, as you see, there are 2 versions of the rear section, The red Supra in the background looks like it has the same type of bumper and the same license plate mounting place as we have them here in Austria, Germany, Switzerland and other European countrys. The other version as seen on the black Supra, doesn't look familiar to me. I thin there's one member here which uses this thingy. (Red Supra, has "SUPRA" painted on this)
Try to send a personal message to our forum member "-Christian-", he's the one here who has and sells a lot of used and new car/spare parts. The only drawback in this: Could take a day or two to get an answer from him, cos he's always busy doin stuff. However, great mechanic (could assemble a 7gmt with the right hand tied to the left ankle.
Keep us up to date
PS: If wou want to talk to a real english speaking person, get in contact with "Matce".
