our speedo needle - yes it will actually come back out the bottom! Best I could draw it in text, but we got the speedo needle to cover the odometer!
4th of July (well 5th actually), was cruising down the interstate at 2AM top down, speedo literally coming out the bottom as described above, 4 lanes wide and not a car in sight. Finally come up on a car in the left lane and noticed crown vic taillights, so slowed down to match it, he was going 85... whoops! Cruised next to him for a mile or so, he eventually slows down, pulls in behind us, then flips on all the hidden lights. Damn!!!
He pulled us over, screamed at me for a bit, I still remember 20 years later, something about how hard it would be to call my mom and tell her how we just scraped your son off the road, blah blah blah... then he let me go!!! We went the speed limit the rest of the way home. Back then I just thought how lucky I was not to get a ticket. Today I realize how dangerous it really was, somebody I know just witnessed the car in front of them hit a deer in exactly the same spot last year (their car was literally covered in deer guts and blood, gross).
edit - all my spaces are taken away so my drawing looks stupid. Just imagine some spaces in between the numbers and slashes to spread them out!
edit two - found a pic. The speedo comes out by the digital tach not the odometer. Forgot about the digital tach!

So our cluster was 0-85 MPH instead of this pic, and we got the needle down to about 5500 RPM! Ahh the memories
