Thank you for the info.
I guess I will have to make my own parts then. The first one will be a back-block or air adapter similar to the phantom, but with an old-school spring adjuster. the next will be a phantom like power tube system. I may just purchase a set of phantom parts to see what it would take to adapt them to the Maverick.
