Below is a before and after of a corroded/collision damaged '68 911 front end. It was hit (you can see wrinkles on the side wall) and severely corroded. I basically put a new nose on it one panel at a time, front pan, latch panel, inner front fender panel, lateral supports, etc. It is finished off with spot welds to look as factory correct as possible (you might have to zoom in to see them). The Celette helped a lot with this repair, it allowed me to pull the shock tower out (it was pushed in from the collision), and put the front pan in exactly the right spot. The car more or less had no nose at one point, so it's great knowing where to put the new one, just bolt it down. One interesting thing to note is that this particular '68 had a gas tank support panel with an elongated indentation under the battery tray. I noticed it while cutting it out and ordered the correct one. I was amazed someone made the correct panel for this year, I think it was only '64 and '68 with the elongated indentation, no idea why those two years.
Please get in touch with me if you are interested in this type of work.
