I used that one Geoff for my 79. It worked very well identifying all the codes. Turns out my van was made in the last 10 days of Bay production in Germany and probably one of the last delivered into California. Saved the info into a MS Word doc.
Hardest part was being unable to see the m-code plate because of the underdash a/c. Used a mirror and the camera and then re-read it all backwards.
Good news is that the van is still original with the exception of the upper body paint - L90D instead of LE1M. That is about to change.
