I think when you don't use the bumper guards, just the plain bumper the turn signals can be left in place. The smaller bumper wil fit underneath the turn signals. Also it wil give a cleaner look without the guards.

While I have no idea what it takes to do it, the attached picture proves that no light or valance changes are needed.

And no bumper guards.

Maybe a black mesh-grille in the valance will make it look good.

I found that my car has two towing-hooks attached to the rear body. Is this a good mounting point for early Z or fiberglass bumpers?

If I'm orienting the picture correctly, you should be able to fabricate some brackets that use those mounting points, yes.

They are located on the inside of the shocks at the point where they go through the bodywork.

For orientation you should rotate the image to the left. It is a picture of the shock/tow mount on the right side of the car (standing behind it).

That's what I thought. In that case, the mounting holes for the tow hooks are similar to the mounts for the early bumpers. You won't be able to use the factory brackets, but it should be easy to build something similar.

You can see the bumper mounts in the picture of my car in the link below:

Looking at the pictures on your site I notice that the indentations on the rear sides of the car stretch more to the wheel arch than the indentations on my car.

The rubber side pieces on my car are shorter than the metal side pieces of the earlier bumpers. Is this going to cause me problems when fitting earlier bumpers?

I don't really know, since I only have experience with the early cars.

I know I've seen information on a website about replacing the late 260Z/280Z bumpers with the 240Z bumpers, but I can't remember where, maybe try a google search?

Thanks Ken, tried that one as well. Came across this thread: http://www.zcar.com/forums/read.php?f=1&i=629325&t=619865#reply_629325

Is this the article you mentioned in your post?
