[AutodeltaGTA]

Bob,
I likewise have an Autodelta car. From 65 though. I also have the airbox that came with the car but have actually never looked at it in detail. I will do so over the weekend and see if i can come up with any constructive input.
Best regards,

Bob,
Here are my pics from what came with my 65 Autodelta car.
Looking on what you have already produced i do not think they will be much help though
If/when available i would be interested in buying one box.
Best regards,
