I got it out - for those who don't know it's kind of a PIA and goes something like this:

- Disco brake pedal by removing under dash panels and retainer clip
- remove strut brace
- remove air cleaner box
- move cruise control assembly out of the way
- remove throttle and cruise cables from throttle body along with the bracket
- move ABS controller and master cylinder out of the way
- remove EGR valve
- remove EGR valve shield after un-clipping wiring harness retainers
- loosen trans dip stick
- On booster viewed from the master cylinder side there is a black tab at about 11:00. Depress and rotate booster counter clockwise to release it from it's mounting bracket.

A real joy, that sucker was tight, but now the orifice tube it all of it's clogged up glory is right there.

Thanks, Howard
