Thank you fellas.

Andy, Yes I have a 21 Lb lithium battery out back with all aluminum power cable connecting it to the firewall junction post. From there on to the starter it's all copper strand.
Years ago when Autometer came out with their lightweight gauges (I think they ae called Autolites) I was first in line for them. They were significantly lighter than the older regular Autometer gauges. I also have a 5" Monster RPM Autolite gauge poking out on a 30 degree angle from the dash where I can see it with the corners of my eyes. It looks like the factory installed it there.

As fas as my instrument cluster, believe it or not, I went into that as well. I stripped it down of all parts, hole sawed the sides to remove the most of that HEAVY cast metal and applied a good 3M tape over the holes. I then painted the whole inside a flat white so that the light could reflect better and reinstalled all my circuits and light sockets etc. IIRC I took off some where between a pound or so.
