1956 Ford Wagon and Others VIN Question

[Jwawhite]

I placed my VIN number into an old Ford vin registry to find out particulars of my Parklane model. Made in Dallas, had a 4 barrel on it, but listed as Customline. Why doesn't the vin distinguish a Parklane? Got to thinking about it, was the extra trim put on during the resto? And then henceforth a Parklane? Finding other vins from Parklanes on-line, they all are identified as Customline.

Any VIN experts out there?
