Pictures "saved as". Thanks for posting those up Phil. I've been stashing 
bits and pieces of info on this since that site that had everything went belly-up.
Haven't had to do mine yet as one light tap on the dash lasts me about 6 
months when the speedo starts bouncing. Will be nice to have that info when the 
time comes though.

Can't have too many clamps (old woodworker's adage) or too many DIY 
postings for '91 200q procedures. Today, one of our listers requested 
specific info pertaining to the solution I used to cure my "bouncing 
speedometer" problem. I sent him a couple of annotated  JPEGS, which 
I have also added to my previously posted web listing for images on 
this topic. The new image files are called "photo_1_solder_fix.jpg" 
and "photo_2_reassembled_IC.jpg" and can be found here:
