Anyone have a problem with fitting a top vent kit to a Harman XXV? I ordered a top vent kit with our new Harman XXV and find that it does not fit over the top lip and align with the pre-drilled holes as described in the instructions that came with the vent kit. Now what? Take a grinder to the lip and make it fit or send it back for a new one. The alignment is off by 1/8" to 1/4" +/-. We bought this in NY but live in VT so not getting much from the local dealer.
