Hello David, thanks for reaching out. The 91603 looks like the correct part number for the pilot assembly but sadly we do not carry these here.

The Replacement Gas Regulator # 91602 is the correct replacement for the Atwood 91043 in your picture if you need to replace the regulator. We used to have them but no longer carry them here unfortunately.
