Hey buddy, seeing as this was just under a year ago, I was wondering if you found at any more info? I have a 19’ Custom Trail Boss as well and most of the infor here is for the LTs. It’s my understanding that the wheel arches should be the same size and therefore what fits the gentleman in the black LT could fit should work for us. But I just wanna make sure before pulling the trigger on wheels and tires that don’t fit. Thanks again.
