A '73 Duster door glass?

Researched this forum hoping for pics to make a comparison with but did not find any that looked like my glass. Trying to determine if my glass/door/regulator is a '73 Duster/Dart Sport specific type or the '74-'76 type. This glass was NOT mounted to post type regulator referred to in other posts I read. More similar to older scissor type regator mounting. Any help appreciated.
