It is not an easy task to align the early rear bumper design to the later urethane bumper car, as everybody knows there are sufficient differences both in body lines and rear side market light locations. The only successful way I found was to make my own mold and build my own custom rear bumper. By doing this I was able to get things to line up and do some slight adjustments to the spoiler height and add a third brake light.

This is the mold that I made

And the finished rear bumper


Here is a side view showing everything pretty much lining up and makes the whole rear end look one piece. The biggest task was building the mold, the actually fitting of the bumper was easy and very little filling was required to blend everything. I am sharing this just to encourage anybody wanting to do this and also concerned about wanting a factory type look that it can be done.

Well done Pzark. Those are some serious fabrication skills you have there.... I’d hazard a guess beyond that of the average diy’er. My 75 has the same rear suspension as you and a pretend 68-73 rear bumper similar to yours.

You may not be aware but there is a guy making fake 68-73 rear bumper caps out of fiberglass. A lot of us have purchased it and bolted it onto a 74 or newer C3.

Yeah I saw those caps they do look good but they wouldn’t give me the look that I was after so after looking at how difficult it would be to try to graft on a cut off early bumper with all the inherent differences I decided to go the easy route and make my own. That way I could put things where I wanted them. There is a picture floating around the internet showing a late model, looks like red colored 82 with the opening rear hatch, it has an early rear end blended on and that car inspired me to. I think it looks so nice and if I can get mine half as good I will be well pleased. I was hoping to paint it this year but have to have knee replacement (getting old I guess) so it will probably be next year now.

chiming in to ask what the current landscape looks like in terms of making fiberglass chrome FRONT bumper bits go onto 73+ cars.

(Edited)

It just strikes me as odd that there isn't a buisness for this, i imagine the demand to made 73 and up cars have that nice chrome front look is very high but there's no supply

Guys, this thread has received a lot of leeway on the repeated references to the sales of a Non Supporting Vendor. I’d rather not close the thread, but will if they do not stop. I’ve removed a couple recent posts and will need to edit others. Please discuss the topic without promoting Non Supporting Vendors.
