Hot Wheels Speed Driver Engine / Bit Holder

The Hot Wheels [Speed Driver](https://hotwheels.fandom.com/wiki/Speed_Driver) shows on the package how it is designed to be used with bits, but there always seemed to me to be something missing: A way to hold the bit in place!

The bit is a 1/4 drive and 2" long. Here is the one I used: https://www.amazon.com/dp/B000RGW0C8

Interestingly, and quite disappointing, is that the newer castings (green and red w/ silver wheels) had the chassis redesigned, and for some reason the 1/4 drive wont fit. I'm not sure if that was on purpose or not.
