I saw a guy with a sickly modded 300zx TT and he had Heads up Display on his winsheild. There was a little box that sat on the dash, and it projected his speed and rpms up onto the winsheild. Anyone out there know about this? Thanks

 

Pontiacs have them stock

 

Yeah, but i think it would be a cool mod.

 

Have a factory one, but at least on the C5 it requires a different dashboard and a different windshield with a reflective patch in the glass. The retrofit for those reasons is not $ viable.
Maybe someone has a aftermarket?

If so it should be adjustable for positon (driver height) and brightness.
Good luck
