V6 mini truck/4Runner caliper casting #’s identification

[abosely]

What are the casting numbers and any other identifing marks for the 86’-94’ 4 big piston V6 Toyota OEM pistons?

I’m looking for some cores to rebuild, but want to be sure to get OEM castings.

Looking for 2 sets of cores in good rebuildable shape if anyone has some.

Cheers, Allen

The defining characteristic is that both pistons are the same size.

Do you have a set of 4 cylinder calipers handy to compare to?

I reread your post. Not sure how to identify castings as being OEM. Do you think it really matters?
