[Tigers] Driver's Side Fender

[Thomas Witt]

Joel,
  Go to this link and scroll down to the image of the Tiger engine bay.  The 
hole (cavity, MSD mount) that is being referred to is the old regulator 
mount (mounting plate shows in this image).  As best I can tell you are 
referrring to an actual 6" hole (round???) in that area with the plate 
removed.

 I assume if I am correct that someone put the hole there as a vent (for 
heat) or had an unusual exhaust configuration - though I would go with my 
first guess.

So, some cars may still have the regulator, some only the plate (or an MSD-6 
and the like mounted) and if the regulator and plate are both removed it can 
look like a cavity, but, no, there is not suppose to be a 6" hole.
