E53 Voltage Regulator Brush Cover Removal

Does anyone know the secret to removing the E53 alternator spindle end brush cover that is attached to the voltage regulator? I removed my voltage regulator and now need to reinstall. It appears to me it wasn't meant to reinstall. The spindle cap has the two brushes going through it. The brushes need to be depressed and set inside the spring loaded cavity and at the same time the cap needs to slide off the regulator housing. Looks like a 3 handed job at least. I cannot see anyway to retract and hold the brushes in the housing. No alignment holes as in other regulators - using the toothpick or paper clip method. What is the secret?

There's a Youtube video on how to rebuild the Valeo (Bosch is similar) alternator. The brush cap has to be removed prior to installing the brush assembly and regulator back onto the alternator. You install the regulator and brushes without the cap and once the regulator is secured with screws you snap the cap cover into place.

Thanks for sending the video. That did the trick. I was able to remove the spindle cover.
