so the brakes were squishy, checked the pads and fluid, everything was good, took it to my mechanic and they said the brake vacuum pump was going. tried to search online and getting mixed results from the search FCP is trying to sell me 5 screws and 2 o-rings for $60, parts geek shows me 2 totally different vacuum pump assemblies. without disassembling the car, is there a way to tell which model i have to replace?

No vacuum in the brake booster would result in a hard to depress pedal, not squishy. Squishy pedal is often an air bubble trapped inside the brake system, or brake pads semi-frozen, or caliper's anti-rattle clip/spring installed incorrectly.

The air can be trapped inside ABS. In that case it can't be bled out without triggering the inlet/exhaust valves in ABS. You need a DiCE/VIDA or other capable scanner to do so.
That is what I thought as well, but being that I listened to the mechanic I ordered both the switch and the vacuum unit to replace, figured if I replace everything now, it will be good in the long run, don't have vida yet, that's the next thing to buy after I install all the new suspension parts I just got
