I have a bone stock Orange 1971 240Z(series 1) never been restored With the bumper end caps. I'm the 3rd owner of the car. I bought her from a collector. I also own 2 other 1971 240Z's and they do not have any bumper end caps. Brandon (purest to the core)
The only thing that matters is as long as the new rails are all one piece running from the back to the front for stringth.in the first picture it doesn't look like it's all one piece. Remember you whole front end are ridding on the rails. The only thing that matters is strength. The welds look great to me. I am by no means a professional welder.
