inside door opener?

[john rod]

first i am unsure what the correct name for this mechanism is.....

i need an inside door opener, goes under the door panel [and not the latch assy.]
classic parts has one [part #18-835], however they list it as a '68-'71 unit only. i have a '67. they do not have a '67 part #.

so can someone confirm or deny that the opening mechanism is the same for '67 thru '71?

i know the '72's are different because the door panel is thicker and the spline shaft is longer. [although if the bolt pattern was the same and the lever length was the same it would probably work].

thanks
