What makes 5 lug tacoma control arms different?

Hi ya’ll! Just recently got myself a 5 slug and after reading a bit through this forum, it appears that the control arms for our 5 slug brethren have been discontinued. Now I’m in a state of mild panic seeing as I have no way of sourcing new control arms should the need arise. Now my questions are

What makes 5 lug control arms different than the 6 lug tacos? And since Total Chaos control arms are discontinued for the 5 lugs, are there any other places for us 5 luggers to source these parts other than the junk yard?

edit:

I’d like to add that I did not grow up around cars and have 0 car knowledge, so just learning as I go. Thanks yall

 

^What's this about? Several mfrs making them still. Just pick the ones that say RWD:

Would a 6 lug RWD CA fit a 5 lug just fine? Thought they had different fitments bc of frame difference. Sorry

edit: also thanks for the link

 

^"RWD" on Rock Auto means 5-lugger. The 6-lugger parts say "Prerunner" or "4WD". As additional assurance, you can always compare the photo in the listing with the arms on your truck.

 

Damn, thank you! I appreciate the help.
