I have a bit of an update on this from a really helpful guy on the samba
1967 are one year only doors, Volkswagen Part # 151 831 051 H for the Left Door and 151 831 052 H for the Right side. These are for 1967 Convertible only. US and Euro will be the same door in this year. The letter reflects the number of versions of a 151 Door. So starting from a "no letter" part number, H would be the 9 th different door version for the Beetle Convertible. For the 051 and 052 portion of the Part Number, Odd Numbers (051) are either Left or doesn't matter and Even Numbers (052) are always Right side. The center three Numbers ( 831 ) are location in the Catalog ( and on the Shelves at a Volkswagen Dealer ). The Right 66 ( G ) Door is a one year only door too, as is the 65 ( E ) Right Door !! But the Left Door is 65 AND 66 and is a ( G ).
Now I just need to find some!!
