Sonic50 - I installed an HUD unit in my '87 Fiero GT last year. But, it is not one from another Pontiac. Last year one of the guys on the forum ( Bob Williams) was making an HUD senting unit which easily connected to three wires inside the instrument POD. The readout was just MPH, nothing else. The unit was tricky to place properly and I used a 1 1/4 x 1 inch piece of glass painted black on the back to reflect the speed back exactly at eye level. The small piece of glass is positioned at the upper edge of the driver's side (of course) speaker grill, just in front of the front window.
The thing works great, is absolutely accurate and is bright and clear, more at nite than in bright daylight which often washes out the reading. I don't know if Bob is still making the units, but his address is:
Bob Williams, 70 Kennedy Drive, Attleboro, MA 02703.
I'll try to take some pics tomorrow and post them or e mail them to you. Ed
