..another cool thing would be to include some sort of center aperture/cut-out for something like a back up camera screen, dash cam or something like your smart phone/device, etc. Something that would be considered a little unusual or advanced for an older truck....but with a very modern swing to it.
If you don't have anything chosen yet it could be 'sized' to correspond with a nice GM logo or equivalent until a device was found and chosen.
....just thinking out loud here.....'spit balling' so to speak.

All Good
