Robert,
     This is quite easy to do on the front suspension.  If you look at 
the points where the lower A-arms are bolted to the frame, you will see 
that there are some shims inbetween.  All you have to do is to add 
shims.  You can either buy the factory shims, or just cut your own from 
flat steel stock.  It is important to retain the shims which are 
already in place, as these also affect the castor angle.  Just add your 
new shims to them, and be sure to add the same amount in all four 
locations.  You will also then need to re-adjust the toe-in.  
     I used to have a '65 MkII which I did this to.  Basically, I added 
as much shim as I could fit while keeping the nut on the stock bolt.  
This gave about 2 degrees negative camber, produced perfectly even tire 
wear on 185/70-13 tires (see my reply to your other message), and 
totally eliminated understeer.  However, inspect the lower trunnion 
bushings freqently (the plastic top-hat shaped ones where the lower 
A-arm attaches to the trunnion), as they were not designed for the 
increased cornering loads, and deform quickly.  I would recommend going 
to harder competition type bushings.
     Are you doing anything to the rear suspension?

     Pete
