Hall sensor replacement

[MA7008O]

Dear, hope you all are doing well.

964 C2 from 1991

I gathered a replacement hall sensor and removed the plate that holds the sensor from the distributor.

The actual sensor if riveted to one plate, which is “somehow” fixed to the other.

Problem is that one of the rivets that holds the sensor is hidden y one of the plates.

Anyone know how should I do it?

Thanks a lot.
