call a shop and ask them, very few if any people on here have both a 4Runner and Tacoma (and have swapped UCA's between them) to be able to credibly answer your question.
A shop that fabricates or distributes UCA's for Toyotas would be able to answer your question. toyotec, wheelers,downsouth motorsports ....
If you're basing a purchase decision on some random guy on a forum's opinion you'll more likely than not be disappointed. Protect yourself and if nothing else make sure they're returnable.
