Late Conversion

Here's a scene from the 1961 movie "The Young Ones".

A Wraith, registration number PYP258, chassis number DLW75.

It's the same number plate as this Ebay car...

And the same chassis number DLW75

Barrett-Jackson states:

'Per the Rolls-Royce Build Sheet, James Young coachbuilder, car made for Walter I. Wolfson of Castrol Oil Co. of New Jersey. Original engine froze and was replaced with same type. Rebuilt transmission. Sale includes spare Rolls-Royce seats and seat side panels. Mechanically very good. Includes valuable and rare "kneeling lady" hood ornament. Right hand drive, rebuilt automatic transmission, small roof window/air intake. Engine changed less than 1,000 miles ago. Per Rolls Royce build sheet, this vehicle was not built as a hearse. Over $38,000 in receipts were spent on body and mechanicals, as well as maintenance and repair records.'

So the question is:

Was the car converted by James Young to a Station Wagon when it was more than six years old?

Anyone...?
