Whoa that's awesome news. I would definitely be interested in doing this mod myself since I've been looking for a reason to swap my cluster (original cluster went bad and haven't gotten around to replacing it with a new ZHP cluster yet). Definitely keep us updated...in the mean time I guess I should be looking on ebay for a manual M3 cluster? Also let me know who can virginize the cluster.
Edit: Also just realized, we would need to mod the cluster for 4 doors in case you have a sedan that you want to do this with correct? If I remember from nextel's build, he had to actually solder in the LEDs for the rear doors.
