Rob, I used a 5/16 because I found a 50% off deal on amazon on them. I always search Amazon before buying anything because they are often the cheapest even on stuff like tools and welding helmets. They had Mallory optical ignition modules when all the race suppliers were out of stock for weeks. I think 3/8 would be better because it allows you to be off center from the spot weld a little more and still get it all. I peeled the other half of the donor last night in 90 minutes. John |

QUOTE(Racer Chris @ Dec 1 2010, 08:23 PM)  You'll have a fuel cell and oil cooler to install as soon as you get the trunk reconstructed and the chassis flipped upright again John. Here's what it looks like mocked up. The tubular braces will be ready shortly. Everything appears to fit together just fine. I have most of your fuel plumbing together now and the cooler/shroud shipped today. We plumbed a similar oil cooler installation over the last couple days for a 3.2L conversion, so I have many details already worked out. Chris, That is looking great. Thanks for all your help with this project. Chris is making the front tubes for me like he did for Jeff Hail, plus the fuel and oil systems. John |

Test fitting the donor chunk.
 It fits pretty well. My goal is to have it fit without any forcing. I want the suspension mounting points to line up without any stress on the jig or the chunk. I have trimmed it little by little and now the fit is pretty good. I wonder if the original unit body parts would just fall together perfectly or if they had to be clamped against their will to take they shape Karmann wanted? Does it help to pre-tension the body panels or would that stress just be released over time as the car went over bumps? I got the oil cooler and shrouds from Chris yesterday, thanks! John |

John,
I bought the fenders for my project car from QRS Fiberglass (cheap plug) and am very happy with the quality and the weight of them. I will take some pix for you |

I have been very busy on the car, just not posting much. Here is what has been
done. I spent several days fiddling with the donor chunk, with levels and a tram gauge to try to get it as perfect as possible. Then I tack welded it in about 10 places on each side. These pictures are from after welding it in more when I was re-checking it all.  I checked measurements from the suspension points diagonally and lengthwise against each other. They are all within 0.5 mm of each other. My tram gauge is only accurate to 2mm so I was happy with that result.    |

The tram gauge makes it easy to measure between two points on the car no
matter how uneven the body is between them.  I bought this gauge from http://www.autobodytoolmart.com/ just for this project. It is too hard to measure between holes accurately with a tape measure and this way I got to buy another cool tool. It should be good for checking front and rear toe measurements as well. When I was satisfied all was ok I plug welded all the drilled out spot weld holes. The existing fender wells are very thin metal with lots of rusted through pin holes and a load of holes the owners drilled everywhere. For added strength, I seam welded a lot of the pinch weld between the donor chunk and the original car. I don't plan on grinding all the welds totally flat. I think that will weaken it too much and the original owners would never have bothered with that.  Notice all the holes in the fenders. After welding the chunk in, I spent days and days filling in all the rust holes and drilled holes I don't plan to use anymore. John |

Fixing some choice holes in the fender wells.
 This was a tricky shape to fix. I used 18 gauge metal which is a pain to bend. All the bends were done using one pair of pliers to hold the piece close to where I wanted to bend it, then using another pair to grab it and bend. Once you start having it welded on, you can shape it by hammering on it or hammering on a screw driver to force the metal where you want to go.  Another similar hole.   |

Welded up.
 Lots of holes welded up. This area I did grind almost flush.  Lot of the same kind of holes on the other side. John |

Just my .02.
While you have it up side over, weld all the pinch seams. Grind the 2 pieces flush with each other then weld the knife edge......that makes the metal as clean as possible and gives a good target to weld (dirty wetal gives blow backs). Dress up with a grinder to make the welds smooth.....no kerfs. All lap seams should be at least (2 inchers) skip welded tho I prefer full welds. .023 wire works best for this. |

JP, I have been thinking of doing more seam welding as you describe.
I especially want to shore up the rear shock towers where they tend to crack. John |

I did find some cracking on my car around the bottom of the rear towers......see pic. (not my car). This was before I put in the down tubes from the cage to towers.
The sheet metal in that area is really thin. Also pictured is the srea over the axles & inner ear. The pinch seams marked are highly susceptable to cracking. The.023 wire I used was called "Easy Grind". It is not nearly as hard to grind (go figure) a normal 6 or 7000 serise wire. It also requires less amperage to run...less heat is gud for sheet metal.....don't weld up your cage with it tho. (IMG:style_emoticons/default/biggrin.gif) Attached image(s)
