Lada Niva flaps for the SAAB. It was like $6 for the pair, and $15 to ship them from Ukraine. They’re a little narrower than the original SAAB ones, and probably not nearly as durable, but they look appropriate, and are the right length.
Won’t get sucked into the tires when reversing through snow or mud. I don’t think they’ll hold up well against rocks and gravel though, the rubber is much softer than OEM, but this won’t be a problem for how/where I drive.
Primarily just want to keep dirt and water from blasting the backs of the tail light housings and wiring, which is more or less exposed (the inner mudguard only comes down part way inside the fender, so lots of road spray just flies up inside the back of the rear fender.)
