Not likely
I have an older tail kit I picked up that needs a design change mod. But this change was done a long time ago. The parts for the mod will be send to me when I buy the wing kit (for free). That said I learned then that the basic designs haven't changed much over the years; if at all. The changes are mainly found in ways that make the assembly easier on the customers such as 'pre-punched' holes. A quick call to the engineers over at the Vans factory answered all (and more) of my question like yours. My impression was they are very generous and genuinely wanted to help me learn and make infromed choices.
There are plenty of real experts on this sight that can answer this question as well.
Best, and good lick.
