You can remove the 2 vacuum lines associated with the EGR, the line from vac source(my 86 is bottom of TB, drivers side) to EGR solenoid (mounted to thermostat), and solenoid to diaphragm.
Just be sure to plug the vac source.

At least on 89, the vac source at the throttle body goes to the solenoid and also runs to the front of the car via a 3-way. I'd say he'd have to cut the vac line on the left at the solenoid and plug that.
Or cut off the 3-way and connect together the throttle body line and the line running up to the front of the car. I've had to use some soft vac line to connect two hard vac lines before. Though I think they sell straight soft vac connector ends for hard lines. The hard lines should be 5/32".

Any pic's? Just don"t want to accidentally delete the wrong ones and find out I'm chasing a vacuum problem

You could probably just run a new piece of 5/32" hard line from the throttle body to where ever that line goes to. You'd just have to get some end pieces. You might could pull the soft rubber ends pieces off the old line and put on the new. This way you could save the old vac line.

You end up with
From rear plenum ports
a line to fuel pressure reg
a line to one way valve for HVAC / cruise/ vac ball
A line from port under TB to the purge system valves under LH head light
I just replaced all the stock plastic lines with with rubber hose where needed
