Cadillac Fleetwood Deville Re-presentation

Hello I am new owner of a Fleetwood, Deville Bj 1984 Is a street limousine with a 4.1 engine and 150 horses. Luckily still has a cardan shaft. Lambda probe has it already, but still a noblebrock carburetor. Engine starts great and has no oil or water loss. Luckily already has an H-deposit and the last TÜV was 2014. Also a special permission for the small license plate is there. There is still a lot to prepare before it goes to the TÜV. are the fenders at the front which dissolve. Who knows where to have such ends?
