Gauge cluster goes to 85 mph..........
WEll that the "top speed" on my gauge cluster in my 82' GS...i know it goes faster than that (because i've tried it)....I've tried searching for this answer but no go...why does my gauge cluster only top out at 85 while i have seen other 7's that go up to 120......Also can i put one of thse 120 mph clusters in my 82?

It is because during the early 80's the speedos were limited by the federal government in hopes of keeping people from speeding. Basically, it didn't help at all, so the speedos went back up a couple years later. You can drop a cluster out of a '83 as a direct swap. I believe they go to 130 mph.

All US cars in 1981 and 1982 have 85mph speedometers. It was the law. The '83 guage is a direct bolt-in. No recalibration required. You don't need to change the entire panel, just the guage can be swapped.

The 85mph speedos rule.
Seriously. If you're going faster than that, you're not going to be looking at the speedo. And the rest of the time, it's nice to be reading across most of the gauge's sweep, instead of only 1/3rd or 1/2 of the sweep.
Prime offender of this is all of the DSMs that had 170mph speedometers. Even the SOHC 1.8l turdboxes. 60mph was around 10 o'clock on the gauge.

The official name is the "Joan Claybrook Memorial Speedometer." Mrs. Claybrook was the misguided bureaucrat also associated with underposted speed limits and chronic lane blocking. She believed it was somehow safer to not know how fast one was going. Even more fun with a digital speedometer, where you could not see the needle pegged. (Contrary to the popular belief, there is no official record of her membership in the **** party.)

Does any one know if the guage cluster from the 81 like onlyonthurs is bidding for on ebay will fit into the dash of a 79-80? I sure would like to update mine i have always hated the fact that the tach and the volt meter are combined into one guage.

I have both and can take pictures tonight.
