Re: Looking for a used SRT Spoiler!
I'm sure you have already looked into this if you are looking to swap wings...but if I remember correctly from when I owned a Limited, if the limited wing is not functioning correctly, the car will limit your speed.
In other words, if you remove your limited's wing - and try to put an SRT wing in its place, the car may have an adverse reaction.
I believe this swap has been done before, but I don't know what it took. So, basically, just make sure you look into it before you swap wings and head on your way - otherwise you may not make it home in time.
