Just use a loooong screwdriver to poke down between the wires on the front and back of the distributor. You'll find a pair of regular phillips screws under that tangle of spaghetti. Transfer your wires from your old cap to the new cap, (one at a time to avoid mix ups) replace the rotor "bug" just under the cap too - screw her back together. Tighten up the screws until snug. No more, no less. Good luck.
