How to change spark plugs, distributor cap and rotor.
Picture #1: Here the brand new distributor cap. I bought it from a Bosh distributor and it was half the price the SAAB dealer sell it. I paid $47.00 cnd for it (2003). Picture #2: Here the inside, as you can see there's only two posts visible. The other two are flush with the cap casing.
Picture #3: Here a closeup of the two post. Picture #4: Here a closeup of the two other post.
Picture #5: Here the rotor. Price was $21.00 cnd from that Bosh place (2003). Picture #6: Here an underside view of the rotor.
