I don't think shipping would be that expensive... Honestly I don't know how much more work would be needed to make it perfect. Ive put some bondo to fill crack. Probably it will need some more glazing putty or whatever they're using to smooth out...
I had it installed with CS Short ram intake. All you have to do is trim the silicone elbow about 3/4". Check the link on first page to see pictures of the box and CS SRI installed on the car. I had it on 08 Mazda 3
