I ordered the mk4 kit for various reasons, but I kinda like the fia 289 dash. I was planning on just ordering a blank dash and then cutting the holes for a 427 competition dash. I might now cut the holes for the 289 fia dash, but realize the gauges are different sizes. Is the fia kit dash aluminum and does it come with the holes already cut? I wonder if Factory Five would allow me to substitute the mk4 gauges with the fia ones
