Here is something you can ponder on - take a look at a 1967 - 72 Ford F-600 dash cluster. When I up-graded my 1965 GMC Suburban - I wanted extra gauges without the "extra" look. I used the Ford vacuum gauge and the mechanical tach in the GMC's large empty circle knock-outs on both sides of the GMC's speedometer - looked closely at the remaining Ford gauges in the cluster and I believe I could have used them to - but didn't. You end up with 3 large gauges in the center and the remaining gauges on each side. These gauges are Stewart Warner gauges so they have the "look". Check out any mid 1960 - early 1970's larger "F Series" (600 -700) ect. dash clusters and see what you think.
