I should think it would not be too difficult to just build/install a "Muffler Stip Rail" that works on the horizontal rather than in the vertical. The actuator/apparatus was available from APSC, (I hope Schaff will carry them!). Make a rail out of light wood, such a spruce. Put slide rods inside the cavity. Wouldn't be that hard. Use the type of strip like the Yamaha type, that are reinforced up to the "strike point area", to off-set "sagging". No biggie IMO.
