he's gopt it becasue from alot opf places you can by whole front ends on pallets! that way you get the engine and all stuff related to it! i dont think they sell them for panels! but as said it is handy seeing as they arent availiable from ford and this way you know they are genuine!
back end was prob crushed as front dont look to badly damaged!
same reason as you dont see 2 halfs of the same car in a scrap yard (cars cut to get people out!) as it would be two easy to cut and shut again!
