This was just asked recently.
The archives should provide lots of info.
I converted my van 10yrs ago.  Details are fuzzy but didn't seem too hard.
The clutch line and/or shifter rod runs under the gas tank I think so you do
have some work on your hands.

Subject: Probably a silly question, but...

How much trouble would it be to convert an automatic vanagon to stick
shift?

Just asking...
