I ordered this as being compatible with Briggs 397358. There should be a rivet with a raised head (space under it) for mounting a metal baffle on the engine. This coil doesn't have one so I am returning it and it could have been easily prevented if the seller had only had photos of both sides! Frustratingly, even the Stens website has only a single photo so you just can't tell.I have ordered a DZE 4026 also from Amazon (which is the actual box that Stens is selling with their own label added). It's $8 cheaper AND the photos show the rivet present. We shall see.Update 11/4: The DZE 4026 arrived today. Sad to say, the photos in the listing for it are wrong, it has no rivets either. At least it is cheaper than the identical one with the Stens label.
