Wow, looking good! I love the renderings. I thought it was a photo at first on my phone.
Are you going to tear the whole thing down for paint now that it is together, or try to keep it all in one piece? I always figured I'd end up doing the custom chopper style build.... get everything together, then pull it all apart of paint/powder coat. What a pain though.
If you were to pull it apart, I really like the Harley Davidson textured black powder coat. It has a great satin look... I plan to use a lot of it on my build.
Also, I like the Audi Aviator Grey color:

If you don't mind me asking, what was the cost to have your half shafts converted from Honda spline to miata spline? Do you have the measurements of both? I'm Curious if my mitsubishi half shafts have enough meat on them to convert over like you did.
