Interesting setup.  Those aren't the Corvette LS1 coils that I have.
Were ther two versions for the Covette, or are yours the version that is
used for the LS1 engine in the pickup (a.k.a., truck)?

Bill,
Here's three pictures of my coils-on-plugs setup, unpainted.  (Lest
anyone get 
the idea of using garden hose for plug-coil connectors, they were for
mockup 
purposes only.)  The brackets mount to the holes in the rotor housings
that 
are normally used for knock sensors.  I understand these bolt holes are
only 
on some of the 3rd gen engines.  So, you would have to find somewhere
else to 
bolt to.  The bracket is made of 1/2" square 4130 tube.  The "wires"
going 
from the coil to the plug cap were made from springs which I stretched
out a 
bit.  Since these coils are made to mount directly on the valve covers
of the 
LS1, I didn't see any reason not to mount them where I did.  However, if
I 
start experiencing coil failures, I will most likely move them, or mount
them 
on the plugs using shock mounts.
