Hi "Lawfish",

Ran across these dash panels from Carolina Customs. I now the speedo size is smaller than you wanted, but thought you might like to see them. They have 5 & ^ hole gauge panels, Maybe they look too "streetroddy" for a muscle car ? The speedo & tach hole size is 3 1/8" & the four other gauge openings are for 2 1/8". That company is ceasing prodction of these panels soon.

The 6 hole panel is 17 3/4" X 4" in size & the 5 gauge panels are: 14" X 4"
