I'm planning the same as you yellow69. I just found a tach in a 1981 Z-28 and was thinking of installing it into the same 3 hole bezel. I have 2 of these so I would like to use this style for that reason.

I was thinking of installing some green lights (Radio shack) for the turn signals into some holes that I'll drill on each side of the center hole. I am also planning on drilling holes in the bottom for aftermarket gauges. Should be much simpler on them doing it this way over installing into existing holes on the guage type bezel.

I haven't attempted this project yet so I can't offer any tips but will be watching this thread closely. If I'm successfull, I'll post my results later this year. Maybe I'll do a step by step picture/story of mine? (winter project for me)
