Thanks dash_cam, that's exactly what I ended up getting and it worked great for connecting the gauges to.
I stopped by a radiator shop and they said that yes, a system that is filled with air will vacuum and carry out the oil with it.
The only way to know for sure is to either
A: measure how much was vacuumed out (not an option for me) or
B: vacuum and fill with air over and over until no more oil comes out, to evac the whole system, and start over.
So, applying vacuum until it's empty might be a way to go.
But let's say I do that, and completely vacuum the system to empty, and then suck all the air out. As for putting oil back in, how is that done? The Freon is compressed and can be connected by a hose. But the oil is just in a pour can. How would the oil be added?
Lastly, this particular shop quoted me $99 for an "Evac and Recharge" plus the cost of Freon and oil, which isn't a bad deal at all.
