Very cool project, and I grew up in a '63 Ghia Convertible, my mom's daily driver from 1973-1982. Black, red/orange interior with white piping iirc, and a white top. My dad picked it up at the factory and brought it back after serving in Germany.
I love this approach to the flares. There was a yellow 914-6 running around in Southern California (and occasionally up at Laguna) with 16x7 or 8 in front and 16x8 or 9 in the rear…but the sides looked nearly stock. Pretty sure the same car was on the cover of VW&Porsche magazine (or possibly European Car) with a number of other 914s. There were a couple of 914s done this way—and really well—up here, too. A dark metallic blue six conversion built by John Holleran with 16x7 and 16x8 951 Fuchs, and a 914 (4?) somewhere in the East Bay with deep (!) VW steelies and dog dish hubcaps that I'm not sure made it out of primer. But those rear fenders sure looked cool…almost like they should have been that way from the start.
I suspect you could start a new thread about your brake upgrade, as it looks very appealing and there are a lot of people who want to move to five lugs and better brakes. I was one of them 30 years ago...back when I was looking through the Richmond Classified Flea Market for Porsche parts. My how things have changed.
Meantime, keep on keepin' on—digging the direction of this!
