About ready to pull my hair out with this one.

It was leaking from the base of the faucet and around the bottom of the collar about a month ago. Figured, how hard could this be, so I pulled it apart, threw the o-rings in a plastic bag and headed to the hardware store. They had nothing, so after three hours of driving everywhere, I finally found a hydraulics shop that was able to match the three o-rings for me.

Took them back home, searched for the faucet manual, but realized the faucet had no model number anywhere. Ended up settling on what I thought was the 7400 series, but the manual doesn't actually specify where the o-rings are supposed to go. Stuck them on where I thought they were supposed to be, but with the water turned on, I was getting worse leaking from around the base.

Called Moen, they sent out a new o-ring pack that was all too high of a gauge for what I needed -- in the photo linked with all the parts, the heavier o-rings on the left of the image are what they sent. The ones on the right are what I pulled off. They swear that particular faucet does not use those o-rings. So I tried with the heavier gauge ones and couldn't fit the spout back on.

Two more calls and duplicate parts were sent out by Moen, a month has passed, and at this point, I've decided I'll just stick with a leaky faucet at this point. However, upon trying to put it all back together, I'm now getting zero water out of the spout, although the sprayer attachment off to the side is working beautifully. The base of the faucet is (of course) still leaking once the handle is lifted, but it's more of a thin spray shooting out from under the base now. It's obviously under some pressure.

Does anyone have a similar faucet, or has anyone worked on one of these enough times you'd be able to give me an MS Paint diagram of what the hell I need to do?

Huge, huge thanks ahead of time to anyone taking a stab at this. Thank you!
