After several test on my own bumper, some little modification is needed. But what is the limit, made a parts better than original or just copy the original. In this case customers feedback are welcome.
To remenber the first request in july 2016 to reproduce come from the Italian guys of jeepheritage company, they sent me a poor sample of original parts.
I will send the final parts now to him, just for check what he think about the result.
After some time to find the right screws size and search screw for plastic and some difficult in this way, I take another way and use parker screws.
