Also other Italian small brand cars use short vin on the parts , chrome trims, brackets, buckets , hoods and all other parts which needs a correct fitment on the body.
Also on the very early Pantera's , later when Ford was involved into a mass production the build of the body's are more precise , with result allo the parts are interchangeable , but it looks that the headlight buckets needs a small modification before the paint job.
