Does the VT320 have a similar pot for width and height?   The width and 
height are off on mine.

Inside on the board.   Google for the VT320 service guide and it should tell
you the alignment procedure.

Cory, be very careful in there.   You are technically astute, and I
know you have a serious knack for this stuff, but there are voltages on
and around that board that are unconditionally lethal.

A finger-to-finger shock will hurt, but a hand-to-hand shock can kill
you.   Keep one hand in your pocket or behind your back when the other
hand is inside that chassis.   Also, never do this kind of work when
you're the only person in the building.

Sage advice!   

Use a non-conducting adjustment tool to trim those pots; not a metal shaft 
screwdriver.
