I was thinking of trying these. Its listed as the "premium" option on Rock Auto. Because they are a beam design they wouldn't look massively out of place compared to a skeletal frame design. Only $7 each so even if they suck its not the end of the world. At least in picture compared to a Goodmark factory looking unit, the Anco looks heavier. Like it might gravity feed onto the windshield better.
Mine work, they are functional but hecka squeaky. They also like to get stuck if the windshield isn't very wet.
