Side Intake Scoops

[Type IV Super]

Hi all,
does anyone know a source for those side intake scoops like those use on Remmele bugs?
I'm trying to find a source and price for them.
I was thinking of using those or fasioning the rear window scoops like those made by http://www.vwinnovations.com
for air intake on the Super. Though they would be functional, I don't know if they would make any difference. I do like the styling they add.
Any info on these guys?

Thanks.
