No, I dont think most people here will fail, but only time will tell who succeeds. Theres a reason that only 3% of the builds started actually get completed. Throw enough time and money at any project and it will get done, but those two things are not the easiest of hurdles for most builders.
Yes, I re-did my wiper arm. I went to the dealership about 3 months ago when Digibeam came to visit. I took alot of pictures and dimensions from a LP640 that was in the showromm, and built from that. Everything had to be fabricated, no donor parts would work.
Alot has changed on my car since it was last seen on the other forums. Windshield wiper, glass engine cover, new LP670 style engine cover, Audi A4 front air-ride suspension, new door cards, new center console, new guage assembly, radiator relocations, new headlights, shiftkit, etc. Not to mention the LP670 changeover is almost complete.
