Hello I just joined this Z car community to gather some data on a 1972 Datsun 240 that I'm helping my son build. We're a little over a year into the project and its currently on a rotisserie. I'm a retired body shop owner and have built dozens of first gen Camaros. This is my first foray into a Japanese automobile. Simple things on an American car such as door latches ,strikers and door adjustments are pretty straight forward. Then comes this car (seems there are some "rubber bushings" missing on the door latch), the reason I'm here. However if I have to deal with these "popups" every time I change a page, I won't be here long. I get the advertisements, but this "download" thing is more than annoying. Is this normal?
