im not sure if anyone has ever done this, but i want to take some autometer gauges, and make my own gauge cluster, so im here to ask, if you think it'd my possible?, and if you say it is, would you use a 3 3/8 or 5 inch speedometer?

Thanks for your input

 

Sure it's possible, I remember JR Asperer building a custom cluster with Autometer guages around 93 in his EF. Personally, I'd use a 5in tach and speedometer if you have room for them.
