You'll do a great job. Quality work is part of your signature. It's unfortunate to see the "quality" that these cars endured during assembly. Granted, if I put on 500 of these gaskets every day, I'd probably slap one on upside down by mistake every now and again. That's where USPS got their slogan "If it fits, it ships.". 🙂
I didn't mean to imply you wouldn't do a great job putting it back together. It'll look way better than new when you're done. I have so many first-world problems that I felt needed resolution, and this was one of them. 😋
