If you are looking for P-51 related stuff go to the swap pages and search just them with using the term "mustang" here is that link as an example:Hmm, I can't seem to find these links near the P-51 anywhere... Anyone got a link..?
I know .. some got confused on the new format so just trying to help (It's also harder to search because things like P-51 won't work anymore). BTW the free add-ons are here but your probably know that : https://www.realflight.com/support/kb/article.php?q=16-1033
