4Afc Distributor Ignition Module

[Suad]

I am hoping someone will be able to help me.

 

I want to remove the ignition module from the housing of the distributor. I can't work out if it is held on by the screws at the front and side or if it is attached by some other means. If it is held on by the screws, they are screwed in so tightly that I have almost stripped the heads trying to remove them.
