I am trying to determine if a 1969 911E, chassis 11 921 0523, would use the older or newer version of the 67-73 Targa top and seals. They changed somewhere in the 1969 model year. Can anyone give a chassis number for the change?

Also, anyone have knowledge of a soft read window setup to convert a glassback into a soft rear window?

Any help appreciated.
