Default Pass side block threaded boss

Maybe a very dumb question, but I’m putting a totally stock 93 motor back together. On the pass side lower front of the block there is a threaded boss. Here is a pic.

This pic is an early engine. On a 93 this is buried behind the EGR valve. Who can tell me what this is for?

Todd,
Here is a photo of a later block.

And the block side of the EGR mounting bracket.

The center threaded boss is not used for attaching anything. Perhaps a left over fixture mounting point from when the block was first machined at the factory.
