I have a better front bumper that came with the car from previous owner as he was starting to do restoration on this El Camino. I took me six years to finally change it.
And at the same time I could install right kind of turning signal lights. It did came with amber lights as it was manufactured, but due to registration progress in Finland the company that handled whole thing from buying, shipping and registration in here had to change those lenses to clear to pass registration. It's illegal for car to have an amber lights pointing straight ahead that are constantly on as driving lights, turning signal can be amber of course, but because those act as dual purpose it had to be changed to get approved by registration.
Thigh space and I needed flex head socket to reach out and of course it was really tight and I had to spray some CRC's rust/general lubrication on those bolts.
As the space was tight I could only loosen it less than tenth of the turn. So it took time and few impacts on my knuckles.
One down and three more to go. After all it wasn't that hard, just a bit of time, turning nut off a bit by bit.
