Hope you got everything fixed. I never heard of a 24hr part store. I know there is nothing like that around here for many, many miles.
But I would imagine that everything is okay. Maybe a little damage to the bearings, but should be okay to drive.
For my similar story, a couple years ago, before I owned my truck, I was driving up through the mountains. I had driven there before, but the snow melt and rain had caused some big ruts. I was doing fine until I caught a rock. Oil pan was fine, but it broke the oil filter housing clean off. Got a ride home. Next day my dad and I stop at the junk yard to get a new housing and head up into the mountain to fix my car. When we get up there, we realized that we didn't have a gasket. We tried to reuse the old one, but it leaked all over. No good. So my dad pulls a note pad out of the glove box of his truck and tears the cardboard off the back. He then takes about 10 minutes to carefully trace and cut the pattern from the cardboard. Put it all back together and it sealed fine! I drove it like that for another 3 years and it never leaked. That was an 87 3.8L engine.
