That sounds awesome. I'd love to see a prictural tour of your Denali inside and out. I'm particularly intrigued with how the shifter swap looks and how much trouble it was to do it.
I'm in the process of a build and mod of an 06 Escalade and am always looking for ideas. So far, have had trans rebuilt, new suspension and steering, did a 2/4 belltech drop kit, and went from stock 17" to 20" wheels off 2018 Escalade.The engine swap to a LS364/450 is happening now, then exhausts and custom tune program. Just ordered new seat covers.
