@05Single I've had the cluster apart several times. The needles were something I did, though I'm unsure where they came from off the top of my head. I do know that they were clear at one time and then I used sharpies to color them green. Sooner (probably rather than later) I'll be swapping LEDs into the cluster due to one of the lights going out, though I'd rather get a cluster that has a closer mileage to what's currently on the Tahoe...
But with the Denali dash surround that I plan to modify and run, I feel I must now get ahold of the matching wood trim wheel, door accents and the console accent in order to tie it in to the rest of the interior...
Still trying to figure out through research if the accent piece from the console can simply be swapped as opposed to having to run the entire console though.
