...are those bubbles used over the turbo a stock piece from somewhere?
I guess they are; I made a mold, might as well make more of them. It's a bit arcane and probably won't be on the KV parts list, but sure, I'll make you one. Contact me at kineticvehicles.com and let me know what you want. I prefer not to do KV business on LocostUSA, this being where I hang out with my friends and swap info and stories.
...either way not exactly what I am looking for but might give me ideas where to look.
To me, the locost sport/affliction is more about finding what'll work on a tight budget than it's about finding exactly what we're looking for, and if we want exactly what we're looking for then we make it. It wouldn't be all that hard to shape a piece of urethane insulation foam into the exact bubble shape to suit your vision, and then cover it with fiberglass and resin (or bang it out of metal) and have just what you want. Look at Dale's car, look at the Rufus Special, it can be done! At heart I think I'm more of a rat rodder, I tend to stop at "this'll do" and rarely shoot for perfect.
One reason I love the vintage race car look is (ooh man, am I going to get comments, or what?) that before the era when they had to write John Player or Marlboro on the cars (that is, before they had to draw big money to stay competitive and looks became a race car's most important feature), real racers were pretty dang slapdash. Good enough to win was good enough, and as far as an homage to the character of Lotus-back-in-the-day, locosts are closer than Caterhams. But back to your question: I don't know of anyplace to buy bubbles of this nature (except for moi, and I only have one model) but I can advise on how to make one yourself that's just what you want.
