I also got one repro,but i dont know from where it comes..It looks like crap.

Dont know have to fix it,its alot of air between the corners of the louver and roof..

So there are 2 different styles of louvers,one for challenger and one for cuda??

Im afraid the paint will crack/get damage if i try the "tweaking" method..

Anyone have a bright idea of how to make it fit better..

Here are some pictures..
