I have this knob installed because I preferred the red lettering over the black on the ITS accessory knob. The base of this CTR knob is larger than the one on the ITS so it fits and works with no issues, but isn't perfectly flush. I think if I could get my hands on the shift boot collar from a CTR without buying a whole freaking assembly it'd work just fine but I can't find how to get one and all the aftermarket ones look too aftermarket and not OEM ish. I'll update with a pic shortly.
