OEM Parts for 2nd Gen Tacomas

I did some digging and wasn't able to find any threads dedicated to sites where OEM parts can be found for 2nd gen Tacomas. This thread will hopefully be that outlet for some such as myself who are searching for reasonable prices on odds and ends that are far too expensive if purchased from the Stealership.
I'm currently on a hunt for O2 sensors both before and after the catalytic converter for my truck (05 TRD Offroad) and I'm having difficulties confirming that the parts I find are the right fit for my truck. Can anybody confirm if Partsgeek or RockAuto carry the correct sensors for my truck? Any knowledge is much appreciated as always!

 

Thus far the widest selections I've been able to find on OEM Tacoma parts are on the following sites:

http://www.partsgeek.com/
http://www.autozone.com/

 

I'm looking for an OEM rear bumper. I have a 2013 Tacoma. I want a magnetic grey metallic(1g3 colo) rear bumper. If any one is selling there's I'm willing to buy or trade if interested.

I used trd4u website to get some OEM parts..

 

Did you Google -> Online Toyota Parts

Lots of dealers sell online - you will find quite a few using the google I just provided. One of the problems with a lot of these dealers who sell online is a lack of good parts diagrams. Another problem is some will charge $20 to ship a push pin that costs .79 cents.

2 of the better places to go to for good diagrams are:

http://parts.villagetoyota.com

Once inside scroll down to the section titled "Parts We Sell" and select vehicle - Year/Model

A good site to use if you just want to look at parts diagrams is:

http://www.partsouq.com

Supply your VIN and scroll thru the list - parts diagrams on the right - part numbers on the left. A fairly good site if you are just interested in looking at parts.
