I have after-market rain guards on the sliding door windows of my 2008 Dodge GC SXT. I'm about to purchase a 2011 Town & Country. Do you know if the rain guards will fit?

I know someone else who went from a 2010 to 2012 and the doors must have changed a bit -- the rain guards didn't fit on the 2012 (and that's why I "inherited" them on my 2008). Just wondering if I'm able to determine if they'll fit a 2011 TC ahead of time. If yes, I'll take them off my 2008 before I bring it in to trade-in.
