the small cluster is a stand alone unit. like 450 bucks or so. they don't have a speedo or tach as far as i could find. they have single setups or that multi style along with all types of senders/sensors. The company makes full oled clusters in custom designs but BIG money.
The units can have their own sensors, or pull info from OBDII which I'd do.
if i can find speedo /tach similar to match id do it in a heartbeat. but if one gauge looks like that and any others are stock, it would just look bad.
I did a quick photoshop...
I am going to contact the company, send them the pic(or a better version of it) and see if they can provide what I need.
I still don't like the center information center being the old style so that would most likely change or be something else.
