Not so sure about deleting the vinyl roof - as Dave said I didnt think this would be something Ford would have done from factory given the relatively untidy way they put on the rear side window filler plate? I thought this was the reason they made them all have the vinyl roof's same as the P5 LTD because of the messy bits on the roof that they hide from sight?
I know two guys with 1973 Landau's - so one of the very first ones made - and they swear they came out with
4V 351 engines... not sure if this is true or not?
