Tearing down this "new to me" TC4 to see what all it needs, and match the setup on it to my current car. After finding that those spare arms are actually from a TC3, I'm starting to wonder about the car. I don't even know what the differences are (something in the steering system?)...
Anyway, I've found another difference that might not be a big deal - look at this:
My existing car on the left, the "new" one for my son on the right. The steering knuckles are different. I looked at the exploded view of the car, and that part number looks like the ones on my car. What are those on the one on the right?
Already see that I've got to order quite a few parts - lots of stripped screws, hidden broken things, etc...
