I have a guy who 3D prints bezels and brackets for the Holley dash. If someone wants to work with him to make one for a Buick let me know. You would have to be able to take some measurements and work with him on fitment.
I have the mini LCD screen off to the right like you see there. I would love to have one installed but was quoted north of 1,500. I probably should have got it done but I ran out of funds. I think I can do it myself, but wiring is one thing I’m afraid of. I should go ahead and do it. I was just about to post how to change out the dull ass dash lights anyway.
