ugh I literally just replaced mine cuz it was rusted out bad. I couldn't find one ANYWHERE cuz they rust out so often, I ordered one from http://wrxusa.com/Suspension.html
their prices are competitive and it got to me quickly. hope that helps
norms isn't that bad just some of there stuff is pricey cause they are going buy the average price on car-parts.com and its not like they dont pay a hefty price for some of those cars from insurance companys and then have to part them out so they are like every other junkyard trying to make a good profit to buy more part-able cars
