On a 2004 polo gnaws at the tailgate of the rust. I have now organized a suitable one at the verwerter. Very well preserved, colour even fits quite well. Not the same, but “time-appropriate” is the keyword. Extensions are always easy, but now it is supposed to be on the car. So far I have changed only one fender and one bonnet, especially with the latter I took quite a long time, until it was properly adjusted. But maybe I also only have the wrong technology + missing experience. How do you go about it most meaningfully? “Setting possibilities” offer on the one hand the screws on the hinges (borings are larger), the lock bracket in the body and the rubber buffers on the tailgate. Where do you start first, build it first and look at it or turn everything into a “base position”… ?
