BTDT... It takes two. People that is.  You need first to make yourself a
gage.  14mm IIRC, (nope... just looked it up... Bentley page 34.4) 3/4"
old (25BH127156) or 7/8" new (after previously nemtioned VIN Number)
wide. I used a piece of a joist hanger, but any piece of sheet metal
will do.

Inside:
Place trans in neutral
Remove shift boot.
align holes in top shift plate with holes in lower shift plate (at base
of shifter.)
Outside:
Remove spare tire.
Remove cover over bottom of shifter.
Loosen clamp on shift rod so that the selector lever can move easily.
Press bottom of shifter to the left (driver's side on US models)
Helper: Insert gage.
Tighten clamp on selector rod.

Works evey time!
