Jim,
I know the story behind this car, and I found the highlighted area too far away from the original car...
...but it is a great car of course, not just because it has a F engine...
And yes, comparing all available pics from the 206 I have found many different things...they were all handbuilt in the 60ies, of course!
I practise O/A welding and it works quite ok now, but TIG is better for thicker panels, some of mine are thicker, some are thinner...so I will do both!
