Single shot load ramp questions

[durango]

I have a model 11 stagger feed action. It is being used for a new build to 6 BR. I want to eliminate the magazine box and install a single shot ramp. Will the SSS centerfeed ramp fit the bottom cutout of this receiver? How can I remove the magazine box without ruining it? Is there any reason why I can't or shouldn't do this? FWIW, I'm building and inletting the stock and hope to eliminate the magazine box to facilitate a full bedding of the receiver bottom.

Does anybody sell the SSS ramp besides SSS?

Thanks, Steve
