This week the rear bumper backdate process begins on the rear bumper now. I’m excited to be working now on a different section of the car finally. I thought the rear would be easier, but that is never the case. The rear reflector panel sheetmetal had to be removed. This part was fairly simple to remove but it did show additional metal work needed in the corners (At the junction between the rear latch panel and rear quarter).
I also quickly realised that the fiberglass mounting brackets interfere with current impact bumper mounting brackets. So I decided to cut these heavy guage parts off with my plasma cutter and accidentally caught a rubber seal on fire. At least I caught it on camera! The bad news I quickly discovered my fire extinguisher didn’t work. I put it out with a wet rag thankfully.
After the parts were removed I weighed them on a scale and was surprised they weighed 10lbs!
Then I trial fit the fiberglass bumper and it didn’t fit well at all. I knew the used bumper I got was from a car with fender flares, but I was surprised how wide the bumper was even at the tailights. I contemplated selling the bumper and starting again, but I cut it into three pieces to make it fit the best I can. Now I believe I’m only going to use the side portions and use the factory steel section in the middle.
So nothing is ever easy especially when building a hotrod Porsche with parts from all over the place and from different year cars. Wish me luck!
After removing all the brackets and sheetmetal needed to backdate the rear it was evident that I needed to finish the corners where the latch panel meets the rear quarter panels. Previously these corners hid behind the large reflector panel, but now they are visible. I decided to weld the seams together and fill/contour the shape with lead autobody filler. Due to the high stress created by the corner and the close proximity to the rear engine mounts I believe lead is superior to plastic filler here. You can see the leadwork in the video below:
