I am Mike and i own a 1970 Mach 1 Mustang that's been collecting dust as i collect parts.
In Hall, NY there is a shop called RodTech. They were at the Buffalo Motorama last year and i expect them to be back for 2019. (March 29th thru the 31st.)
The look ok, but 2 things, First, wrong sizes, I have 4 x 2.625" (2 5/8") and 2 x 5" holes; secondly, i'm not crazy about the white faces, as i am trying to match my original clock. (Black face with whitish numbers)
