I have a GM Overhead Console like we used to modify for application in an ImpalaSS. It is in it's original condition and never butchered.
If memory serves me, the install was pretty straight forward and instructions are probably still available in the archives somewhere.
I originally got this one for my last SS but never put it in. The car is long gone but this has been in my shop ever since. If anyone is interested, I'll take either $100 or something of like value in trade. (plus shipping) photos available on request
