Why can't you post exact dimensions of your tanks caps and cartos. That way I would kow if a tank would fit my existing steel caps the other way around. I would love to see the inner and outer dimensions and the lenght of the tank. And when it comes to caps, what inner dimension would they fit.
When it comes to cartos XL and XXL and regular, I am comfused, why not just put the real dimensions?
