Brian, you're another person to say its the plastic front shock tower
That bar piece came from the Wide Bumper set, the holes line up perfectly where the top bumper piece goes onto the front bulkhead, but is too thick to go there. I don't think it would actually go there, but so far that's the only place I can see it fitting
Not even sure if I've put on the Wide Bumper set on properly or not. Im sure I have, but something says I've got something wrong/missing.
