Maxwell, the Crossfire tumbler assembly is completely different. I didn't get a real good look at the back side of it since I didn't have to dig around under the dashboard, but what I saw didn't look anything like the pictures in the link.

I did a lot of searching on the net and there are no write-ups on how to do this procedure on the Crossfire / R170 platform. I take that as a good sign since it tells me that M/B may have finally solved the problem. It seems to be very common in older models. Like I said in my earlier post, the tumbler/switch assembly appears to be very stout and looks & feels like it was machined out of a single piece of billet aluminum. There's no plastic on it that I could see.
