Tach Issues...

I was wondering what the redline is for the GS's, my stock tach says its 7k, but i bought aftermarket blue guage backrounds and they say its 6,500k, instead of 7k. The stock tach also goes up to 9k, and my aftermarket only goes up to 8k. I just wanted to know which was correct, because i know i ordered the right guage backround, but there is a big difference in the rpm range. Thanks

The 5spds redline at 7k and hit the rev limited around 7200. The auto redline at 6500, not sure what they rev limit at. So basicle you bought gauges designed for an auto tranny. Now if the numbers are in the same spot as before then the tach wont be off but if the numbers aren't in the same spot it will be wrong.
