just have the muff shop make you the replacement piece and bolt it on yourself.. the truck does not even have to go down there..just print out the pic in the link showing the complete system.

provide them custom size/measurements after you have a chance to have a look under there with a tape measure.

they can make one right up faily cheap I would think.. offer 40-50 bux...about the same if you buy/ship it...ifin you could get one..
