I've finished R&D on the WK shifter assembly and have great news...
I can change the colors of your WK shifter assembly to Red, Green, Blue, or Amber, to match your switch colors.
Actually, it's been a go for over a week, now, but I wanted to secure a parts order for this job, before I announced it.
I can offer you a total shifter package with the shifter and the 4WD Low/N switch.
Here's a pic of the job in Blue!
I can turn this particular item in 24 hours, for you.
