So I bought a 370Z the previous owner apparently broke the B pillar finishers before I even owned. Was frustrated about the cost for a new B pillar finisher, and how thin the clip brackets are on this part so I designed my own replacement bracket. Seems to be a common problem, so I've uploaded the design to thingiverse for anyone to download free! If you have access to a 3D printer its a very cheap fix for a stupidly expensive and common issue.
I'm not selling these, or intend to profit from them in any way. Anyone can print the design. Upload to shapeways or other 3d print service if you dont have a printer or know someone who does. If you're in the Los Angeles area PM me and I'd be happy to run you off a set.
I forgot to get a picture of the back after installing my printed brackets, but I'm sure the other one is in the same condition so I'll try to get a little guide uploaded when I do that one if anyone is interested.
