Here's a photo of the "other" side. As you can see there are a handful of washers that help to space out the striker so it aligns. I assumed that was done during fine tuning of the assembly - suggesting that the wedge MUST be able to be removed and put back in. If it was "cast", why would there be adjust ability via washers?
I'm wondering if I can weld it somehow back together until I get a new assembly. It's almost as if there should be a set screw of some kind holding this thing on, but there isn't. See the other photos that show a close up of the "non threaded" area. I'm trying to figure out a way to drive this car on SATURDAY for a final event of the season.
