I'm currently building a set of bands to attach my meg. I'm using a set of steel 55s and a flexible hose between them as a manifold. Then the standard back mount regulators and long hose. These bands will spread the tanks away from the scrubber and the dill and o2 will mount back on the unit. The width is 18 Inch (1.5 inch) wider than a standard set of 104s The hight is 1/2 tall then than a standard meg. I don't want to sling bail out because I prefer to jump off the back of the boat redy to dive. Despite what the mainstream breather buys say. It takes far to long to put on and rout hoses on side mount bottles is rough conditions. I'll send you some pics
