Head rebuild, missing bushing on intake manifold. Or am I?

[Tunnelboy]

So had heads redone and have put everything back together. When I got to the intake manifold, there are these bushings in the corner of the manifold. Presumably so you don't crush the plastic corners. I seem to be missing the back passenger side. Looked all over. Looked online and don't see the part.

Then I looked online at someone selling one and his shows the bushings in the corners except for that corner? I'm wondering if it's supposed to be empty? Anyone know offhand?
