I don't know if there was an error on the HB side. All I know is that I had pre-ordered the spur gear based on description from Tower Hobbies (this was even before HB updated their website with parts). Suddenly when they were going to complete my order, they were going to send me the gear shims. It was a heads up for all those that probably wanted a spur gear instead of gear shims.
Somewhere, someone switched the two part numbers.
