Definitely a huge change from "before" to "after", well done indeed!
A couple of comments: I really like the carpet on the back panel. I don't recall seeing anyone do that before(?) and to me it looks much better than other upholstery coverings. I also like the two tone interior theme, as well as the custom dash. Same for the Camaro bumpers, I have an idea for a similar bumper mod but I'm undecided because I really like the bumperless look too. To be completely honest I've never been a huge fan of the carbon fiber look, but you did a very clean job of it. Something I've been considering is another "wrap" type treatment for the top's exterior. I've always thought the VW radiator conversion is a good idea, and adding a fan shroud is definitely preferred - something I seldom see on these cars for some reason. Overall excellent skills for the entire build. I have to ask, what happened to the rear end (damage)?
Regarding the Joker shift ball. I'm assuming is isn't a pool ball, but a custom shifter knob. There are a few companies that make shifter knobs that look like pool balls but have all sorts of custom emblems on them. Mostly a "hot rod" thing, so many of the designs are along the old school American theme (skulls, flames, devils, spade, Lucky, V8, etc). I can't recall the names of the companies that do them, but a Google search should work.
So what's next? Is this one finished or do you have more ideas? If it's finished, what car will follow?
