I remember them. Always thought it was odd they sold a 170mph speedometer when the factory 160 was a direct bolt in and came in a lot of Firebirds.

The style of lettering (font) was different on the later 70's, '80, & '81 speedometers when compared to the more basic style font used on the mid '72-74 160 speedos.

Though I sure wanted a correct font 160 mph speedo in my '80, there were other things I was spending the $$$ on. Ended up putting a nice used 160 speedo in it around '83. On the '80's i found it easiest to take the Dremel tool & make a narrow small notch in the lower left hand edge of the 160 speedo so it would align propperly with instrument case "sandwich". On my friend Cary's modded '81 turbo, we sent an '81 speedo to a company out in N Hollywood CA, & they rescreened it as a 160 speedo.

That's true .... Although being a working teenager I was happy to settle for the cheap factory 160 mph speedo and "blue'd" out the dash lights. Years later as I kept upgrading engine that turned higher RPM, I'd burry the 6k tach. I had a custom 8k tachometer built using a factory tach face and retained my original quartz clock. I thought that was so darn cool I had to build a 4" stroke 455 that would spin to 7,400 RPM just to make use of the 8k tach ..... And never realized until now (since you pointed it out) my fuel & volt gauge don't look right.
