I was on Ebay browsing through the Firebird/Trans Am today seeing that were real busy here at work, anyway I came across two 94 Trans Am with the 115MPH speedometer cluster

. I thought all the V8 models had the 155MPH cluster? Was there something different about the 94 year? Somebody want to shed some light.
Since I can never post a web page correctly, here are the item numbers on Ebay if you want to check it out:
