I ordered grab handle decals on amazon for 14.99. They send you 2 in case you mess one up and have many different color options. I installed using a pair of tweezers to position the letters before pressing them in place.
RED anodized aluminum knobs are $15-18 on EBay cheap way to add some color & contrast to the dash of the JL it’s a nice touch that you see and appreciate EVERY time you get into your JL
You can get them in most JL colors
I bought two of these Molle panels for the front seat head rests. $9.98 each https://www.amazon.com/gp/product/B07JHZGB1X/ Fits perfect and blends in well with the darker seats. Looks way better than the picture with the tan seats.
