Wavebox & Magnet - Help?

[Armando]

I am feeling very stupid right now but i can't figure out how to attach the wavebox the the mag holder.

The holes in the mag holder (6080.50) are too small, the two pins in the wavebox won't pass through

It is a very tight fit, but the pins go into the round holes and the small rectangular bars go into the holes that have the tabs and say push to release.
