Tim-
I can only answer part of question #3. I'm using Autometer Pro-Comp black=faced gauges (5" speedo and tach), and 2-5/8 engine gauges. I think they look great. They were easy to install, but I ordered a blank dash. I cust the holes using a flycutter I bought from Home Depot for $10. Requires the use of a drill press though.
