sounds good.
Keep some never-sieze for the stainless motor bracket bolts.
Mine seemed to be getting siezed up after a couple adjustment sessions.
I have it, like a dummy I didnt bring it up on the roof when I did the install. They'll probably snap off if I need to move it in the future.
The Sm312d motor had different bolts that did not act this way, or my batch on the
HH120 were suspect to start with.
