Ford Revers glow gauge kit
 

this product http://mustangtuning.com/muelgaset9v61.html the speedometer goes up to 150 on it so i think it might be for a GT. i have a V6 that only goes up to 120. so i would like to know if i could hook that up without a problem? like, would my gauges automatically readjust,or ahh im so confused. sorry. all i need to know, is can i hook up the gauge. thankyou.

They are probably just showing you the v8 gauge as an example. If it says it's for a v6. It'll have 120 mph. And no, it won't re adjust.

If the product you selected is for a V6 then it will be for a V6. Chances are we only had images of the GT gauges, so we just decided to use those instead.
