I found that the GMC cluster was hard to find in AZ cracked, brittle and broken. I was going to use it for a mold anyways. However, I changed my thought and decided to go with all equus guages. I like them and not too expensive. It is amazing what $6 dollars can do for your dash.
$1.00 for 1/2 MDF scrap
$5.00 for patch of suede
had a can of spray glue and spent about 45 minutes fabbing it up and cutting it.

Very cheap looks great.
