Is the dash cluster required while driving?

I'm considering pulling my dash cluster and sending it to that chap on here that will solder new LEDs. I would still need to drive my truck while he has the cluster. I have a scan gauge, so I'd have a good idea of my speed and my full levels (as well as other engine vitals). I'm curious, no so much on the legality, but if the truck requires anything within the cluster to operate properly. I am pretty sure the odometer readings are located within ECU and not actually stored in the cluster.

Am I missing anything here?

 

PreRunnerSeth is the chap that does them, in case anyone else is curious.

Sockmonkey drove his without and reported no vital problems

 

Well how about that. The guy I was referring to showed up. I'll probably take my dash apart this weekend and send it your way. Would you prefer to discuss my ordering here, or via PM or email?

 

you can shoot me a PM or email. Either way works fine.
