Has anyone successfully installed the kit and managed to make sense of the instructions?

The booster has four mounting bolts, but there isn't corresponding holes in the chassis. The instructions just say slide booster through four holes in front of pedal box. I don't mind drilling holes, but I want to make sure I am doing things right. Also it says the lower steering shaft bearing may need to relocated to inside of firewall.

It would be fantastic if someone has some good photos of all of this because I am struggling!
