1966 C10 Window Regulator

[welch_41]

I've been searching and searching and can't find shat about window regulator repair kit for a 66' C10. The regulator as a whole is in good shape but the teeth on the small sprocket are worn and tend to lock up going either direction. Will the regulator repair kit for a 67' work on a 66? The repair kits for models up to 64' don't look like what I pulled out of the door. Repair kits for 65' and 66' do not seem to exist. However, the kit for the 67' looks real close but that only goes as far as looking at a picture on a website. Thanks in advance for the help.
