Hey man that is the OG Green Dragon, looking sweet!
Just double checked Realoem, for my 9/2003 build and for the LCI build (I used 9/2005 as build date) all the shifter part numbers are exactly the same. I guess that was the "cutoff month". But you are correct, all early 5 speed models UP TO 9/2003 have this style shifter:
1 Mounting point on the shifter arm as opposed to 2. My build day is 9/18/2003 so I'm guessing I have the dual mount shifter arm, but if for some reason I don't, and I only have that one bushing on the arm, I would DEFINITELY get a UUC delrin replacement bushing (oval) for that arm to tighten up the feel. Thanks for pointing out GD that for the prior - 9/03 builds (5 speeds) that you may want to invest the 25 bucks in the Delrin bushing for that arm.
Will update this thread when I get to work on the install for mine.
