So for awile now ive been thinking of ways to install a HUD in my 86 t/a. It would be nice with the 4thgen dash.They are easy to wire up to any GM car really. After trying to find a way to mount it on the dash there just isint enough room with the small 4th gen pad. It could work bu placeing it in ther middle but then I would loose defrost vents. I was thinking I could mount it on the headliner between the t-tops and create some sort of mirror effect and possibly flip the screen so it wont read upside down. Think its possible?
