Virgil & Sue,
Thanks for your reply. I had emailed Carlos in Sept. of 2016, but did not hear back from him. I’ll send another email.
In the meantime, I’m also checking out http://www.rushgears.com/ Have any of our members had experience with their work? Apparently, I can send in the stripped smaller gear from my wiper motor and they will either have the same or make the same.
