Just to update:

The new Guard 5th gear is in and all is back together. Took the car on a 20 mile ride. The gear noise is not very noticeable. I certainly can here it but nothing at all to worry about. The car drives great with a large reduction in rpms!

At 3200 rpms I am at 100 MPH
At 3500 rpms I am at 110 MPH.

This will solve any rise in radiator temps on the highway. Next step is to create my heating for the car. The air conditioning works wonderful but I have no heat to help defrost the windows!
