Looking for OEM power locks

I have a '91 Civic DX hatchback. I'm looking to find OEM power locks for both doors if possible. A friend said that DX model didn't have power locks but maybe EX or others did. I want to know what makes and models I need to look for. I have access to many junk yards to search.

I prefer having the OEM look but if not, I do have access to aftermarket hardware.

The EX, LX Sedans came with the power options, you could pull the hardware, relays, wiring out of that and put it in your hatch, but its much cheeper to just pop by a pep boys and get a set of actuators for your locks ($10ea), or go to a car audio shop, they will have em too. You could just then pick up a set of genaric switches for your door pannels, this would me more cost effective and probably more reliable, as aftermarket parts tend to have better construction than a 15 year old power lock.
