looking for 4x4 parts!

I'm looking for any used 4x4 parts bc I am in the process of converting my 07 taco pre runner to 4x4. I need all that is needed to convert over; axles, driveshaft, hubs, transfer case, front diff and everything else. If anyone knows where I can find all this at then please let me know. Thanks!!

 

Check your local junkyard. Also might be easier to buy a 4x4 truck

 

No I dont wanna buy a 4x4 bc that'd be even more money to buy a new truck than it would be to buy the parts for the 4x4. Im a certified master technician and I know exactly how to do it all but im just trying to find everything I can for the best deal before I just buy it. You know what I mean lol. I love my truck to much and have done to much to it just just sale it so im just gonna keep it and convert it over.
