Dunno what they should look like, but looks like they fit, or have been modded to fit ala Strat - Secured on the underside of the pick guard, with 2 screws thru for hight adjust, rather than screwed to the body ala P or J.
Maybe the silicone and plate was to try and hold the windings in the covers, rather than foam under
Must admit i was surprised when i realised that P pups were not fitted like a Strat, as that is what i came across first.
