G'day Dean,
Welcome to the world of "lack of significant parts for 4 door vehicles".
In Australia where 4 door sedans are the norm, that is what was only available here, trying to locate simple things like weather strips for 4 door cars is virtually impossible.
Until the Coupes and Convertibles are so far out of anyone's price-range, and the "lowly" Sedans have to be resurrected, only then will the parts suppliers fill the requirements for these parts.
The only way to obtain the required parts is to either make it yourself, or find a donor vehicle. And, the problem there is that too many Sedans have been used as donor vehicles for Coupes and Convertibles in the past, that the special parts for these vehicles have been simply tossed out, as they didn't fit the initial needs of the restorer.
Bruce.
