These diagrams, thanks to S&2B's (site host) and TMoss (author), might help.

One

Two

Note that Tom based them on a SD '88, but they might get you close (depending upon your year).

Good luck.
 
Stock is almost 20" hg.

2" would leave one with no brake assist, as Go4it noted.
Ensure your vac gauge is accurate.
