Vanel is correct, but every time that I've emailed Randy to notify him of a mistake in my order he has promptly corrected it.
Every time.
I clone a lot of classic rockets, so I order a lot of parts. The problems I've had are mostly dealing with wrong, not missing parts.
Notify Randy if you never received an order. I'm confident he will send you a replacement.
