Do I need some sort of EGR spacer?

You will have to run a solid throttle body spacer. I run accufab 70mm t/b with their solid spacer on mine when I deleted the egr.

I may be wrong, but I think the only thing you need on the egr spacer is the mounting holes for the TB cable. You could probably just fab a spacer out of flat stock steel with the mounting tabs.

Do you have a plan for plugging the egr passages in the lower intake/heads.

What is the reason for getting rid of the EGR? There is no performance gain to be had at wot by ditching the egr, and a potential for timing issues at part throttle.

Some still pitch it claiming it looks cleaner, but I wish I still had my system in place.
