New At This

I've located the source of a problem I'm having with my driver's side
window. Three teeth in the large, crescent-shaped, double-sided gear
that's part of the window regulator are fully or partially stripped.
The regulator motor seems fine.

I can get a new regulator MINUS motor for about $85 (though they quoted
me $51 two days ago...).

It starts to look like I have to take off the current regulator, remove
the motor from it, install it in a new regulator, and reinstall the
regulator in the door. But...I have no real idea what I'm getting
myself into. My Clymer manual sure doesn't cover it. I have the door
panel off, but the regulator seems set in away from the four or five
openings in the inner side of the door. I want to say "How hard can it
be?"; but I haven't even located the bolts that secure the regulator to
the door yet.

Any ideas about difficulty level? Any hints or tips? And -- ideally --
any instructions on how to proceed on this model (96 Civic HX coupe)?

Any assistance appreciated; thanks.
