Porsche 911 GBG Backdate Part 2


With Part 1 of the build page getting too long, welcome to Part 2 of the Porsche 911 GBG Backdate


We left Part 1 with Olly having fitted the heater tubes and new sills and we pick up the project in part 2 with the biggest task to date, the removal of the roof!



With the roof off the guys set about removing the rust that was underneath the roof skin ready for the new skin.
We have also removed, cleaned up and welded in new metal to get rid of the old bits of corrosion that the previous company had just patched over without cutting out the rot first. You can see below from the photos how bad this was.
The new roof skin was then trial fitted with the rest of the panels to see how they all fit together. Big Al has spent a quite a bit of time making sure all the panel gaps are perfect before they all get welded spot welded on.
As we highlighted in part 1 the top of the drivers side door frame was hitting the roof of the car even when adjusted the door to its lowest position, so the roof had to come up slightly. Al has used a hydraulic Porta Power ram to adjust the roof gaps to allow the doors to now shut nicely. Al also has had to shave a bit off the bottom of the doors to get the gapping perfect.
Once we were happy with the gapping the panels were then spot welded on.
We weren’t happy with the way the wheel arch swages looked, with the new Turbo arches swage looking a bit on the thick side. So Al has reduced the thickness on the rear wings and has added a swage to the front wings so that they match the rears. I have to say it has definitely improved the whole look of the car.
We dropped the car back down on the deck and were not happy with the gapping between the edge of the extended front wheel arches and the wheels. The wheels just didn’t sit centrally in the arches, there was just too big of a gap on the one side of each arch, due to the extensions that had been fabricated prior to the car coming to us. There was no option but to cut up the front arches and extend them on one site so that the gapping around the wheel was equal all the way round. We will now have to use a bit of filler here as the budget didn’t allow for new front wings.
With the wing extensions finished we set about getting the front bumper to sit nicely with them. The bumper had been supplied with the car and already had some pug work done to it. To get it to sit nicely with the wings, we had to cut the bumper in half and then adjust both pieces until we were happy with the lines. We also chopped off a huge chunk of the pug that was now jutting out.
To be continued…..
