Jr., no and I'm pretty sure that would be another "no" from Porsche Classic.
These knobs are not replicas, just inspired. I don't see why Porsche would really be interested in them, though... If they wanted to talk about balsa/birch replica's...
Looks like the first Rennshift knob has been installed. I don't have pix, but hopefully they will be posted soon. My beta-tester had to do a little sanding on the inside of the bushing to make it fit, so I have to enlarge the I.D. of the bushing hole slightly, but other than that, it's a go!
