sources of parts in the seattle tacoma area

So I decided to replace my water temp switch today,.yesterday i called around and found a store that had all my parts in stock! When i got there they had none!

So i drive around a little bit and find the switch, so i think. I go home , a wrnch slips , crunch goes the sensor next to it! I finish pulling off the swith and its like , hmm, its just a cap with a sensor in it and doesnt look anything like the one I bought.

So I set that aside and take out the one I broke, JACKPOT. The wrong part was for the one I broke!

Anywasy,.after driving around for a few hours today to get a few parts and order the temp switch. Im lookin for a place in the seattle tacoma area that might carry all my needs.

Anyone have any ideas?
